Why does this small C program crash?

Question

The program is:

#include 
#include 
int main(void) {
    char *a=\"abc\",*ptr;
    ptr=a;
    ptr++;
    *ptr=\'k\';
    printf(\"         


        

Answer 1

This:

char *a="abc";

is really:

const char *a="abc";

You can't modify ptr, which points to the same address as a.
