Answer 1

#include <stdio.h>
#include <string.h>

int main() {
    const char *const myString = "ABC";

    printf("%s\n", myString);
    
    // warning: passing argument 1 of 'strcpy' discards 'const' qualifier
    // strcpy(myString, "XYZ");
    
    const char *myString2 = "UVW";
    // error: assignment of read-only variable 'myString'
    // myString = myString2;

    return 0;
