Question

What is the information the prototype provides to the compiler?

Answer 1

The prototype above provides the following information to the compiler:

1. The return value of the function is of type long.
2. Fact is the name of the function.
3. The function is called with two arguments:
   • The first argument is of int data type.
   • The second argument is of double data type, int display(int, int) // function prototype//.

The above function prototype provides details about the return data type, the name of the function, and a list of formal parameters or arguments.
