Function overloading is a feature in C++ that allows multiple functions with the same name, but different parameter lists, to be defined. This means that you can have multiple functions in a program with the same name, as long as they have different types or number of parameters.
example:
#include <iostream>
using namespace std;
void print(int num) {
cout << "Printing an integer: " << num << endl;
}
void print(double num) {
cout << "Printing a double: " << num << endl;
}
void print(char c) {
cout << "Printing a character: " << c << endl;
}
int main() {
print(5); // Calls the function print(int)
print(3.14); // Calls the function print(double)
print('a'); // Calls the function print(char)
return 0;
}
