What will be the output of following C program?

main()
{
char g[] = "zambiatek";
printf("%s", g + g[6] - g[8]);
}

(A) zambiatek
(B) rzambiatek
(C) zambiatek
(D) forzambiatek

Answer: (A)
Explanation:

char g[] = “zambiatek”;  

// g now has the base address string “zambiatek”  

// g[6] is ‘o’ and g[1] is ‘e’.  

// g[6] – g[1] = ASCII value of ‘o’ – ASCII value of ‘e’ = 8

// So the expression  g + g[6] – g[8] becomes g + 8 which is  

// base address of string “zambiatek”  

printf(“%s”, g + g[6] – g[8]);  // prints zambiatek

Hence, option (A) is correct
