Which of the following statements are correct about the program given below?

#include <stdio.h>
int main ()
  {
     float k = 0.7;
     if (k < 0.7)
         printf ("C\n");
     else
         printf ("C++\n");
     return 0 ;
}

1. The program will output C
2. The program will output C++
3. Compiler will report an error saying a float cannot be compared with a double.
4. Output will be C for 16-bit compilers and C++ for 32-bit compilers

Correct Option: A

if(k < 0.7) here k is a float variable and 0.7 is a double constant. The float variable k is less than double constant 0.7. Hence the if condition is satisfied and it prints 'C'
