How to Pass Parameters to Functions

[super soaker]

Can any one tell me how to Pass Parameters to Functions? Most of the time, i pass const reference parameters to functions, like this:

class One
class Another;

class Example{
   public:

Parameters, also referred to as arguments, are the elements on which a function executes its code,When we introduced Functions we talked about passing parameters to functions. At the time, we were not able to pass more than one array to a function. You can pass parameters (values) to a function. You can then use these parameters for processing the function. You use the values within the function block (statements within the function).

In C, by default, all function arguments are passed by value, and the called function receives a copy of the value passed to it. When you create your own functions, it is often helpful to pass parameters to the function. In Fortran, by default, arguments are passed by reference, and the called function receives the address of the value passed to it.

#include <iostream.h>
double square(double value){
  value = value * value;
  return value;
}

int main() {
  double b = 2.0;
  double b_squared = square(b);
  cout << b << " squared is: " << b_squared << endl;
 
 
  b_squared = square(b);
  cout << b << " squared is: " << b_squared << endl;
 
  return 0;
}
