  • Question
  • What will be the output of the following program in 16 bit platform assuming that 1022 is memory address of the string "Hello1" (in Turbo C under DOS)?
    #include<stdio.h>
    
    int main()
    {
        printf("%u %s\n", &"Hello1", &"Hello2");
        return 0;
    }
    


  • Options
  • A. 1022 Hello2
  • B. Hello1 1022
  • C. Hello1 Hello2
  • D. 1022 1022
  • E. Error

  • Correct Answer
  • 1022 Hello2 

    Explanation
    In printf("%u %s\n", &"Hello", &"Hello");.

    The %u format specifier tells the compiler to print the memory address of the "Hello1".

    The %s format specifier tells the compiler to print the string "Hello2".

    Hence the output of the program is "1022 Hello2".
