Cannot modify C string

Question

Consider the following code.

int main(void) {
    char * test = \"abcdefghijklmnopqrstuvwxyz\";
    test[5] = \'x\';
    printf(\"%s\\n\", test);
    return EXIT_         


        

Answer 1

Do:

 char * bar = strdup(foo);
 bar[5] = 'x';

strdup makes a modifiable copy.

And yes, you should really test that strdup didn't return NULL.
