printf("%d %d %d",sizeof(str1),sizeof(str2),sizeof("abcd"));

main()

    {

    char *str1="abcd";

    char str2[]="abcd";

    printf("%d %d %d",sizeof(str1),sizeof(str2),sizeof("abcd"));

    }

Answer:

2 5 5

Explanation:

In first sizeof, str1 is a character pointer so it gives you the size of the pointer variable. In second sizeof the name str2 indicates the name of the array whose size is 5 (including the '\0' termination character). The third sizeof is similar to the second one.
