C Programming
Questions related to the C Computer Programming Language. This ranges all the way from K&R to the most recent ANSI incarnations. C has become one of the most popular languages today, and has been used to write all sorts of things for nearly all of the modern operating systems and applications. It it a good compromise between speed, power, and complexity.

It is the first node in which the lymphatic drainage occura in a particular area.
Which error is the violation of grammar rules of a programming language?
Syntax Error.
which means that the command makes no sense in the designated programming language.
It is usually followed by a line reference to help a programmer or debugger to locate the syntax flaw.
What number will the function return if the input is 10.5?
Cannot be answered universally; it depends on the function.
Which parameters and design choices determine the actual algorithm of a Feistel cipher?
Block size: Larger block sizes mean greater security but reduced encryption/decryption speed. A block size of 64 bits is a reasonable tradeoff and has been nearly universal in block cipher design. However, the new AES uses a 128-bit block size.
Key size: Larger key size means greater security but may decrease encryption/decryption speed. Key sizes of 64 bits or less are now widely considered being inadequate and 128 bits has become a common size.
Number of rounds: The essence of the Feistel cipher is that a single round offers inadequate security but that multiple rounds offer increasing security. A typical size is 16 rounds.
Sub key generation algorithm: Greater complexity in this algorithm should lead to greater difficulty of cryptanalysis.
Round function: Again, greater complexity generally means greater resistance to cryptanalysis.
Yes because I am an Entrepreneur and I am a risk taker.
Write an c program of addition of two values?
#include<stdio.h>
#include<conio.h>
main()
{
int a,b,sum=0;
clrscr();
printf("Enter two variable:--");
scanf("%d%d",&a,&b);
sum=a+b;
printf("Sum of %d+%d=%d",a,b,sum);
getch();
}
Program to check whether the entered number is even or odd?
#include<stdio.h>
#include<conio.h>
void main()
{
int n;
printf("ENTER NO FOR CHECK........ ");
scanf("%d", &n);
if(n%2==0)
printf("Given No is EVEN");
else
printf("Given No is ODD");
getch();
}
How do you decide the use of one of the three loops in C for a given problem?
The for loop should be used when there is a progression over the members of an array, or where there is a clear initialization, termination-check, and increment. If the block simply has to execute until some condition occurs, use a while loop. The do loop should only be used when the loop must execute at least once, and even then sparingly. It is harder to understand, since the test occurs at the end (it is more like a simple goto).
What are the contents of Audit Program?
contents of audit program are as,
1. a review of system of internal check.
2. audit of balance sheet.
3. audit of p&l a/c.
4. the details of various audit works to be performed and their classification.
5. preparation of audit report and co-ordination of all above mentioned items.
What is flag controlled while loop?
A while loop evaluates a conditional expression at the start of each iteration. If the conditional expression evaluates false, execution passes to the statement that immediately follows the body of the loop. If the conditional expression evaluates true, the body of the loop executes one iteration. When the end of the loop is reached, or a continue statement is encountered within the body of the loop, control passes back to the while statement where the conditional expression is re-evaluated. If a break statement is encountered within the body of the loop, the loop terminates and control passes to the next statement. If a return statement is encountered within the body of the loop, the loop terminates and control passes to the calling function.
while (expression) {
// repeats until the expression evaluates false
}
The braces are optional when the body of the loop is a simple statement. Compound statements must be enclosed in braces.
A flag-controlled while loop has a simple conditional expression that evaluates a Boolean value:
bool x;
// ...
while (x==true) { // flag-controlled loop
// ...
}
}
The above loop can also be written without the equality operator:
while (x) { // flag-controlled loop // ...
}
Moreover, any integral type (such as int or char) will implicitly convert to a bool such that non-zero values evaluate true and zero evaluates false. As such, any integral type can be used in a flag-controlled loop.
What does the initials C.C. mean after a person who is a Free Mason?
User-defined (typedef) and compound types are possible. Heterogeneous aggregate data types

What is data structure why is an array called a data structure which are the other data structures?
A data structure is a collection of more than one elementary item, in some kind of aggregate organization.
An array is a type of structure where more than one item of the same type are arranged serially in memory, and accessed using an index. The item can either be an elementary type or it itself can be a structure type.
A struct (not to be confused with the use of "structure" in this answer) is a type of structure where more than one item of the same or different types are arranged serially in memory, and accessed using the structure member (.) operator.
A union is similar to a struct, except that each member occupies the same address. This means that only one type of data can be stored at any one time in a union.
A self-referential structure is a type of structure, usually constructed of simpler structures, linked together with some kind of pointer scheme. Examples of this are the linked list and tree.
Difference between loop and array?
A loop usually referred to the program flow control with possible repetition of executing the same codes, an array is an abstraction of fixed size container. 2 different concepts.
What is the best type of data type for storing shoe size?
Well, recall that shoes can come in half-sizes. That eliminates integers (and similar).
The best data type would be a float.
How do you connect an ODBC link through C and C Plus Plus?
make sure to include the lib, to your space, or main, or however you are adding in your libs....
define and instantiate an odbc object. use a command such as objectname.connect, wrap it up in a conditional. If you need it to loop for some real time like update needs...thats acceptable.
Write a shell program to find out the avogadro number?
cho "Enter A Number :" read n r=n s=0 rem=0 while [ $n -gt 0 ] do rem=$(($n%10)) s=$(($s+$rem*$rem*$rem)) n=$(($n/10)) done if [ $r -eq $s ] then echo "The Number is Avogadro" else echo "The Number is Not Avogadro" fi
I doubt that somebody has hacked your PC. There is a virus which renames file extensions, by the way it's a very old virus. I recommend you to try to find a good antivirus and repair files.
Why is return statement not necessary when function is called by reference?
return is not necessary if the return type is void, and you want to leave the function only at its end.

1.memory read
2.memory write
3.i/o read
4.i/o write
