 cout << "The 1st result is:" << result << endl;

 cout << "The 2nd result is:" << result << endl;
 result = 3*rankfun(number1,number1);

Look at line 3 -- it says it all.

[ravi_14]

type name ( parameter1, parameter2, ...) { statements }

Where:
- type is the type of the value returned by the function.
- name is the identifier by which the function can be called.
- parameters (as many as needed): parametes.
