Function overloading that differs in return type not necessarily throws an error?

Question

The below code has 3 different return types for same function name and runs with no error.

#include <iostream>
using namespace std;

int printNumber(int y) {
cout << "Prints an integer: " << y << endl;
}
float printNumber(float x) {
cout << "Prints a float: " << x << endl;
}
double printNumber(int x, int y){
cout << "Prints a double: " << x + y << endl;
}

int main() {
int a = 16;
float b = 54.541;
printNumber(a);
printNumber(b);
printNumber(a,b);
}
