C++ Function Overloading

Function Overloading

With function overloading, multiple functions can have the same name with different parameters:

Example

int myFunction(int x)
float myFunction(float x)
double myFunction(double x, double y)

Consider the following example, which have two functions that add numbers of different type:
 

Example

int plusFuncInt(int x, int y) {
  return x + y;
}

double plusFuncDouble(double x, double y) {
  return x + y;
}

int main() {
  int myNum1 = plusFuncInt(8, 5);
  double myNum2 = plusFuncDouble(4.3, 6.26);
  cout << "Int: " << myNum1 << "\n";
  cout << "Double: " << myNum2;
  return 0;
}

Instead of defining two functions that should do the same thing, it is better to overload one.

In the example below, we overload the plusFunc function to work for both int and double:

Example

int plusFunc(int x, int y) {
  return x + y;
}

double plusFunc(double x, double y) {
  return x + y;
}

int main() {
  int myNum1 = plusFunc(8, 5);
  double myNum2 = plusFunc(4.3, 6.26);
  cout << "Int: " << myNum1 << "\n";
  cout << "Double: " << myNum2;
  return 0;
}


Try it now


Note: Multiple functions can have the same name as long as the number and/or type of parameters are different.
