Question 5 Explanation:
char g[] = “geeksforgeeks”;

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

// 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 “geeks”

printf(“%s”, g + g[6] – g[8]);  // prints geeks
Hence, option (A) is correct
