  1. Compiles with no warning and error messages

  5. Hi I am Robot
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

This is the correct option  because in this program we are calling the function displayout(), but we haven’t given its return type. So in the compile time, the compiler will throw an error that “Displayout was not declared in this scope”.
