Discussion Forum : Pointer
Question -
Determine Output:
main()
{
char *str1 = "abcd";
char str2[] = "abcd";
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: Option C
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 'null' termination character). The third sizeof is similar to the second one.
