//Both loops will print out the alphabet {A-Z}

int i = 65;

while(i<65+26)

{

System.out.println((char)i);

i++;

}

...

for(int i=65; i<65+26; i++)

System.out.println((char)i);

As you can see, both loops accomplish the same thing. A while loop simply has a conditional statement that tells the loop what needs to be true for it to keep on looping.

A for loop is more concise: it has 3 parts: a starting value, a conditional statement, and a(n) action for what the loop should do after every iteration (in this case increase i by 1).

The average heap short complexity is O(log n)

You would have to use the Regula Falsi Method formula to prove that the answer is 1. There are two different types when it comes to the formula; simple fast position and double false position.

calloc operator,malloc operator

An example might help:

if (exp) if (exp2) stmt2 else stmt3

equvalent with this:

if (exp) { if (exp2) stmt2 else stmt 3 }

if that's not what you want, use {braces}:

if (exp) { if (exp2) stmt2 } else stmt3

The answer is yes, you can install as many anti virus programs as you want. However, with more than one it will run significantly slower and in the end, there is no advantage with having multiple virus programs as most have the same virus recognising database. I would recommend Norton Internet security, however AVG free edition is increasingly popular and free.

write a program to multily 3*3 matrix.

the value of 0 is '1'.

No, it use memory, just like any other variable.

If you press Ctrl+Alt+Delete, open task manager and then click processes and find the exe file that the program uses to run in the list and terinate it. (In MS Windows).

It has nothing to do with C-language, it simply means that when you press a key representing a character, the character appears on the screen.

In compiler theory, dead code elimination is a compiler optimization used to reduce program size by removing code which does not affect the program. Dead code includes code that can never be executed (unreachable code), and code that only affects dead variables, that is variables that are irrelevant to the program. Consider the following example written in C. int foo() { int a = 24; int b = 25; /* Assignment to dead variable */ int c; c = a << 2; return c; b = 24; /* Unreachable code */} The variable b is assigned a value after a return statement, which makes it impossible to get to. That is, since code execution is linear, and there is no conditional expression wrapping the return statement, any code after the return statement cannot possibly be executed. (This would not be the case if there were a label after the return statement, which opens the possibility of there being a jump that places execution after the return statement.)

That's what you call 1:n relation. An example is the 'father of' relation: everyone has only one father, but any male can have zero, one or more children.

Structure alignment relates to the way objects in memory must be allocated according to the underlying architecture. For instance, a machine might expect an int to be aligned upon a 4-byte boundary. If that is the case then a structure with a member int must be aligned upon a 4-byte boundary and the int member offset from that boundary by some multiple of 4 bytes.

Consider the following:

struct X_ { char c; int i;

} X;

assert (sizeof(X)==sizeof(int)+sizeof(char)); /* oops */

Assuming sizeof(int) is 4 and sizeof(char) is 1 and that an int must be aligned on a 4-byte boundary, the actual length of this structure must be 8 bytes, not the 5 we expected. If it were anything other than 8, then an array of such structures would have misalignments in 3 out of every 4 elements. Note that in order to correctly align this structure, the compiler must insert 3 padding bytes immediately after the char member. This ensures that the int member is offset 4 bytes from the start of the structure. So long as the structure itself is aligned upon a 4-byte boundary (which it now will be because 8 is a multiple of 4), the int will always be correctly aligned.

Inserting padding bytes between members can often increase a structure's size far more than we might expect, particularly if there are many members. To avoid this, it is best to declare members in order of size, largest first. In this way, whenever padding is required, the padding is more likely to be placed at the end of the structure rather than between two or more members.

struct X_ {

char c;

int i;

char c2;

} X;

Given the same criteria as before, this structure would be 12 bytes in length. But by changing the order of the members, we can reduce this to just 8 bytes:

struct X_ {

int i;

char c;

char c2;

} X;

The reason this works is because a char can always be aligned on a 1-byte boundary, so two consecutive char members will easily fit inside a 4-byte word. Thus we only require 2 bytes of padding instead of 4.

Note that it is never safe to assume the lengths of any data type in C other than char which is always sizeof(char)==1. The lengths of all other types are measured in terms of a char, but will vary from system to system according to the underlying architecture. Always use the sizeof() operator to determine type lengths. Note that the sizeof() operator computes data type lengths at compile time, so there is no runtime cost, nor is there any need to store the return value.

C language doesn't say anything about graphics, it is platform-dependent.

A binary tree can be empty, or consist of three parts: a 'value' (any type), and to binary trees, called as 'left child' and 'right child'

A character type (char) is not an integer, but it is an integral type and can therefore be used to store integers and perform integral arithmetic. However, in order to output the value as an integer rather than as a character code, the character must be converted (cast) to an integer. This can be done explicitly or implicitly. The only thing to be wary of is when mixing signed/unsigned representations as this may cause narrowing.

You may use one of several open source compilers and code editors (or even IDEs) to develop and compile C++ code that will operate on a Mac.

I dont know which OS you are referring

In Linux in the shell you can run the following command

df

In Windows, you can click My Computer and press right click the drive what you want and select properties which shows the size, free size, occupied size etc
