c output

Question

Consider the following C program segment:

#include <stdio.h>
main()
{
    static char*s[] = {"black","white","yellow","violet"};
    char **ptr[]={s+3,s+2,s+1,s},***p;
    p=ptr;
    ++P;
    printf("%s",*--*++p+3);
    
}

          

What will be printed by the program?

• et
• ite
• ck
• yellow

Answer 1

++ p means p points to S+2
*(--(*(++P)))+3

++P : address of S+1
*(++P) : S+1
--(*(++P)) : S
*(--(*(++P))) : Address of 1st element of array i.e. Address of 'b'
*(--(*(++P))) + 3 : address of 'c'

now Print string starting from 'c' i.e. 'ck'
