Does this mean that when we allocate memory through malloc, the garbage value will stored at that memory location. When we allocate memory through calloc, every variable will initialized to 0.

exactly I do not understand what it means "initialize it to zero"

If we want to store value of five integer we need 20 bytes so malloc function will allocate 20 bytes to store five integer value...

Hi guys,

#include<stdio.h>#include<stdlib.h>...

What I think is

Why the size of P is 4 after Release memory?

P = 10
P = 4 ...

#include <stdio.h> void addition (int a, int b)

#include <stdio.h>#include <stdlib.h>



int main ()
{
int *P = NULL;
...

But I am passing two actual argument in main function
gone through following links
Too few arguments to function (C language Error)

oh Thank you What's wrong with code


#include <stdio.h>
void addition (int a, int b)
{
int c = a + b;

printf ("c = %d /n", c);
