Overloading functions

Function overloading in C++ is a powerful feature that allows you to define multiple functions with the same name, as long as they differ in their parameter list—either by number, type, or order of parameters. It’s a form of compile-time polymorphism, meaning the compiler decides which version of the function to call based on the arguments provided.

In C++, both float and double are used to represent floating-point numbers, but they differ significantly in precision, memory usage, and range.

double has a higher precision

In C++, the return statement is used inside a function to send a value back to the caller and to terminate the function’s execution. It’s a fundamental part of how functions communicate results.

In programming, the caller is the part of the code that invokes or calls a function.

invoke something (computing) to begin to run a program, etc.

#include <iostream>

using namespace std;

int add(int a, int b) {

    return a + b;  // 'add' is the callee

}

int main() {

    int result = add(5, 3);  // 'main' is the caller

    cout << "Result: " << result << endl;

    return 0;

}

In programming, a parameter is a variable used in a function or method definition to represent the input that the function expects when it's called. It's like a placeholder that gets filled with actual data—called an argument—during execution

// C++ example

void greet(std::string name) {  // 'name' is a parameter

    std::cout << "Hello, " << name << "!\n";

}

greet("Alice");  // "Alice" is the argument

static_cast in C++ is a type conversion operator used to explicitly convert one data type into another at compile time

std::to_string is a handy function in C++ used to convert numeric values into strings.
