What is the overloading functions

Question

with examples

Answer 1

So C++ allows you to give your function more than one definition of itself.
Like this:

#include <iostream>
using namespace std;

class printData {
public:
void print(int w) {
cout << "This is an integer: " << w << endl;
}

void print(char* c) {
cout << "This is a character: " << c << endl;
}
};

int main(void) {
printData p;

p.print(5); // prints out --> This is an integer: 5

p.print("Hello, world!"); // prints out --> This is a character: Hello, world!
return 0;
}

Answer 2

In object oriented programming you can overload a method ( function). I'ts usefull to create a consistent and clean semantic to build your application.
Example:
teacher.update(name)
teacher.update(age)

assuming that name is a string, and age is an integer
