Function Overloading in C++

Function overloading is a feature in C++ where two or more functions can have the same name but different parameters.

Function overloading can be considered as an example of polymorphism feature in C++.

Following is a simple C++ example to demonstrate function overloading.

#include <iostream> 
using namespace std; 
  
void print(int i) { 
  cout << " Here is int " << i << endl; 
} 
void print(double  f) { 
  cout << " Here is float " << f << endl; 
} 
void print(char const *c) { 
  cout << " Here is char* " << c << endl; 
} 
  
int main() { 
  print(10); 
  print(10.10); 
  print("ten"); 
  return 0; 
}

Output:

Here is int 10 
Here is float 10.1 
Here is char* ten
