Modifying a char *const string

Question

I know that const char * is a pointer to a const char, while char *const is a constant pointer to a char. I am testing this in the following code:<

Answer 1

If you want to test it properly, initialize the strings in a function so the initialization can be dynamic and use strdup() for that.

int
main(int argc, char **argv)
{
    char *d1 = strdup("hello");
    char *d2 = strdup("world");

    const char *s = d1;
    char *const t = d2;

    ...

    free(d1);
    free(d2);
}

The d1 and d2 variables are mainly used so that the dynamic allocations can be properly freed using free() at the end. Also, as other answers suggest, always treat string literals as const char *.
