amazon — Fri, 16 Jan 2009 16:45:20 GMT

struct a
{

struct b
{
int x;
int y;
int z;
}bb;

struct c
{
......
......
......
}cc;

struct d
{
int i;
int j;
int k;
}dd;
}aa;

now the prob is given address of dd.i get the address/value of x....
(and no sizeof plz......)

A DOUBT REGARDING COMPILERS

goldberg — Mon, 17 Nov 2008 14:33:15 GMT

I observed that when I allocate some memory dynamically
If I use gcc compiler the values are initialised to 0 for integers , NULL for pointers and so on
But this is not the case when I use DEV C
Can sum1 plz explain me why is this so
And also If there are some other differences between gcc and DEV C can someone plz list them.....

stdout vs stderr in fprintf

shivang — Sat, 30 Aug 2008 19:42:33 GMT

The following program doesn't "seem" to print "hello-out". (Try executing it) #include #include int main() { while(1) { fprintf(stdout,"hello-out"); fprintf(stderr,"hello-err"); sleep(1); } return 0; } What could be the reason? I don't know the answer.

Suppose you type the following program in Linux and then Compile it using a gcc compiler int n; char str[80]; printf("enter a number: "); scanf("%d", &n); printf("enter a string: "); gets(str); printf("you typed %d and \"%s\"\n", n, str); but the compiler seems to be skipping the call to gets()! This is just an example There are other cases too.. Most of the people might be knowing why it happens This ...

a simple one....try this...

try this without actually running the code....

Copy a program

Admin — Sun, 10 Aug 2008 15:05:50 GMT

Write a program to copy its input to its output, replacing each tab by \t, each backspace by \b, and each backslash by \\. This makes tabs and backspaces visible in an unambiguous way.

HOW MANY *'s

SwitchCase — Wed, 13 Aug 2008 15:42:36 GMT

#include
int main()
{
short i=0;
short n=42;

for( i=0;i printf("*");

}

CAN U TELL THE NO OF STARS THAT WILL BE PRINTED?

Sizeof structure

Admin — Sun, 10 Aug 2008 15:02:16 GMT

struct a{
int b;
char c;
float d;
};
struct a1{
int b1;
int c1;
float d1;
};
main()
{
printf("%d %d",sizeof(struct a),sizeof(struct a1));
}

Both the sizes come to be equal on gcc compiler.Why is it so?
