How linked lsts can be usd to represent long integers?
linked list consists of data nodes, each pointing to the next in the list. An array consists of contiguous chunks memory of predetermined size.
Linked lists are quite flexible. They can grow to any size -- up to resource limits -- and each node can be a different size. Memory allocation for a node is done as needed, usually when a new node is added.
Linked lists can be circular, or doubly-linked (pointers forward and backward), and new nodes can be inserted anywhere in the chain.
The greatest downside to linked lists is sequential access: to find any node in memory, each previous node must be examined and the pointers followed. Linked lists are also more complex to program and manage.
Arrays are fixed in size, so resources must be anticipated and consumed in advance. Each element is the same size and must contain the same data type. But access to a particular element is very fast, because its location in memory can be determined mathematically and accessed directly (offset from start of array = subscript * element size).
Note that modern languages -- especially OO languages such as C++ and Java -- blur this distinction by providing classes which offer the best of both worlds. Arrays can grow; linked list complexity is hidden from the programmer; hash tables (special arrays, really) allow for rapid indexing of arbitrary data. But under the hood, each complex data type is implemented using primitives such as arrays and linked lists
Converting machines are used for cutting and packaging large production materials, usually roll stock, into smaller, more usable shape and sizes. Converting equipment includes rewinders, slitters, and sheeters, and can also convert roll stock to sheet stock. Converting machines are categorized by the type and size of the original material, the processing speed, and the configuration and size of the output material. Output material is also often packaged in boxes, cartons, or pallets for shipping and distribution.
What is a logical disciplined approach to programming?
Use Software Engineering techniques, specifically UML, to design the structure of the program before-hand. Then you know how different classes within the program (assuming you are using an Object-Oriented approach) need to communicate with each other, and you've broken the whole program down into the smaller more manageable chunks that need to be written.
Which is better encryption algorithm among DES Blowfish and MD5?
MD5 isn't a encryption algorithm, it's a hashing algorithm.
Encryption will 'hide' the meaning of the encrypted text, while MD5 will 'add up' all the text to come up with a number. This number can be compared to another time this file was 'added up', to provide a simple kind of check to see if the text has been changed or if it is the same.
You are referring to default arguments. However, C does not support default arguments. That's a C++ feature.
What are the advantages of using typedef in a program?
1. Readability. Just like naming your variables properly can show how you intend to use the variable, renaming the type can help show how you intend to use all variables of this type. It eliminates the possible bug of incorrect argument ordering (e.g. if a method signature has multiple boolean flags).
2. Portability. On different systems you might want to have the same variable name (because you're using it the same way) to be of a different type. So you keep the typedef in a header file controlled by conditional compilation (for example) for maximal portability. 3. decreases complexity for declaring complex and repeated declarations like typedef unsigned long int UINT64;
What is the use of extern variable?
External Variables are declared outside all functions, yet are available to all functions that care to use them.
Features of external variables :
Storage : Memory
Default Initial value : zero
Scope : Global
Life : As long as program's execution does't come to an end
Although I do not know the exact context in which the question arose, it might very well have arisen from a simple confusion between HMS CARRON (D30) and the fact that the despatch vessel HMS SURPRISE started life as an order for HMS LOCH CARRON which was changed subsequently to HMS GERRANS BAY and then completed as SURPRISE.

What are the advantages of using variable costing?
ADVANTAGE OF VARIABLE COSTING 1. Inventory changes do not affect profit. 2. Phantom profits are ignored. - Profit resulting from inventory buildup, not sales, is ignored. - When absorption method reports phantom profits, it fails to account for expenses related to carrying the additional inventory. 3. Cost-volume-profit relationship - Facilitates c-v-p analysis by separating cost behavior. - Aids management in solving problems involving choices, e.g., make-or-buy decisions where it facilitates comparing company costs with the costs of buying from outsiders (we'll see this in week 6). 4. Marginal products - Variable costs correspond closely with current out-of-pocket expenditures for a product. - Provides sharper focus on the profitability of products, customer, territories. - Multiplying the volume of an item by its unit contribution margin discloses the relative importance of a product's contribution. 5. Impact of fixed costs - Easier to identify impact of FC by separating it and not burying it in inventory or cost of sales. - Helps management to control operating costs by separating them from COMMITTED COSTS. - Responsibility accounting is easier under VC. As VC does not allocate fixed costs to products, it simplifies tracing costs by lines of managerial responsibility. 6. Pricing policies - Contribution margin approach provides guidelines for the most profitable pricing policies. - In the long run, pricing policies should focus on AVERAGE FULL COST, and in the short run, CONTRIBUTION MARGIN. DANGERS OF VARIABLE COSTING 1. Many are accustomed to the functional income statement, the normal relationship of sales to total costs and to using gross margin and net income data. 2. May assign variable income a broader significance than it has. - When sales is greater than production, higher profits may mislead management into taking improper action. - When production is greater than sales (esp. at the onset of recession when sales lags production), the decreased profits may mislead management as to the severity of the recession and lead to missed future profit opportunities. 3. Over-emphasis may lead to improper decisions regarding relevant costing. - If company drops items contributing small amounts of profits, the fixed unit cost that other products must cover will increase. Thus, profits will likely decrease if company fails to add other products to its line. 4. Difficulty in separating cost behavior. 5. In light of the greater proportion taken up by fixed cost in an automated company's cost structure, the practice of eliminating fixed costs from products becomes questionable realistically and theoretically.

Which function is used to reproduce another copy of the official receipt?
Without knowing which specific software product you are referring to it is impossible to say what function reproduces a copy of the official receipt. Please be very specific when asking questions.
When can't selection structures be represented in CASE?
When the case statement represents a non-constant expression or a non-integral type. The switch statement's expression must be of an integral type or of a type that can be unambiguously converted to an integral type.
Which type of search (linear binary or hash) would you use for the following scenarios?
Explain why you would choose that type of search, ensuring that you illustrate what characteristics in the scenario limit the type of search you can perform.
1. You are looking at a departures list in an airport (which is always sorted by the city the flight is going to) and you want to find your flight to Ottawa in the list.
2.You have a record of visits to your website, organized by the visit time. You want to find when a specific person last visited your website, and are given the person's name.
3. You want to find a textbook for a specific course in a bookstore, where the store is organized by subject.
How do you write a recursive procedure that returns the smallest value in an array of 10 elements?
The operation you describe is not a recursive one, it is iterative (linear in nature). It's also better to return the index of the smallest value rather than just the value itself. In this way we know the position of the smallest value as well as the value itself.
To find the smallest element in an array, we start with the first element. Being the only value encountered so far, it must be the smallest, so we store its index. We then compare the value at the stored index to that of each of the remaining elements, one by one. When we find a smaller value, we update the stored index, because that value is the smallest encountered so far. When we reach the end of the array, the stored index will tell us which element was the smallest, so we simply return that index.
The algorithm can (and should) be generalised to cater for arrays of any length.
// Returns the index of the smallest value in array a of length n
int smallest (const int* const a, int n) {
if (n<1) return -1; // sanity check: the array must have 1 or more elements to be valid
int i, j;
i = 0; // assume first element holds smallest value until proven otherwise
for (j=1; j<n; ++j) if (a[j] < a[i]) i = j; // update i each time a smaller value is found at index j
return i; // a[i] holds the smallest value in the array
}
int main (void) {
const int max = 10; int a[max] = {5, 4, 6, 3, 0, 7, 2, 8, 1, 9};
int i;
i = smallest (a, max);
assert (i==4); // a[4] holds the smallest value
return 0;
}
What are example files of data encoding?
Not to be flippant, but every file is an example of data encoding. Before data can be stored in computer memory or in a disk file, it first has to be digitally encoded in binary. The binary encodings can then be further encoded using encryption or compression.
What expression would test for a length between 10 and 20 meters inclusive in c programming?
if (length>=10 && length<=20) {
// length is between 10 and 20, inclusive...
}
What is a variable that has been declared and automatically initialized to zero.?
It really depends on the programming language. In C and C++, all built-in types are initialised to zero when declared static, otherwise they are uninitialised. In Java, however, all data types are implemented as objects and are therefore initialised at the point of instantiation according to whichever constructor is invoked.

How do you unzip a file programmatically in C programming?
The simplest method is to invoke a third-party unzip program via a system call. If you don't know if the required unzip program will be available on the target machine, you will need to licence an open source unzip library such as 7zip. This will allow you to unzip without making a system call.

What is the difference between you equals 10 and you equals equals 10 in c language?
The = operator is the assignment operator.
The == operator is the equality or equals operator.
The = operator is the assignment operator. We use it to assign a value (the right hand operand) to an object (the left hand operand). The value must be of the same type as the object unless the value can implicitly convert to the object's type. If not, we must explicitly cast the value to the appropriate type. The operator evaluates to the value of the object after assignment, thus creating a temporary value that can be used in other expressions.
Examples:
int you;
you = 10; // assign the value 10 to the object named 'you'
int me, you;
me = 10;
you = 10;
Note that the second example can also be written:
int me, you;
me = you = 10;
This is because the expression 'you = 10' evaluates to the temporary value 10 (the value of 'you' after assignment) which we then assign to 'me'. Operators are evaluated according to operator precedence, and assignment 'chains' like this are always evaluated from right to left.
The == operator is the equality or equals operator. We use it to determine if two object's have the same value. If so, the expression evaluates true, otherwise false. Operators that evaluate true or false are known as Boolean operators (functions that return true or false are known as predicates).
Typically we use the == operator in conditional expressions:
if (a == b) {
// code to execute when the value of a is equal to the value of b
} else {
// code to execute when the value of a is not equal to the value of b
}
while (a == b) {
// This code will loop repeatedly so long as a is equal to b at the beginning of each iteration
}
The == operator is one of six Boolean operators that can be used to compare object values:
== : equal
!= : not equal
< : less than
<= : less than or equal
> : greater than
>= : greater than or equal
