We could initialize a character pointer like this in C.
char *c="test";
Where c points to the first character(t).
But when I gave code like below. It gives segmentation fault.
#include<stdio.h>
#include<stdlib.h>
main()
{
int *i=0;
printf("%d",*i);
}
Also when I give
#include<stdio.h>
#include<stdlib.h>
main()
{
int *i;
i=(int *)malloc(2);
printf("%d",*i);
}
It worked(gave output 0).
When I gave malloc(0), it worked(gave output 0).
Please tell what is happening
