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);
return 0;
}
Output :
Here is int 10 Here is float 10.1 Here is char* ten
