C pointer initialization and dereferencing, what's wrong here?
- by randombits
This should be super simple, but I'm not sure why the compiler is complaining here.
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char *argv[])
{
int *n = 5;
printf ("n: %d", *n);
exit(0);
}
Getting the following complaints:
foo.c: In function ‘main’:
foo.c:6:
warning: initialization makes pointer
from integer without a cast
I just want to print the value that the pointer n references. I'm dereferencing it in the printf() statement and I get a segmentation fault. Compiling this with gcc -o foo foo.c.
