## Overview
In C++, a **parameter** is a variable that is defined while creating a function.  When a function is called, these variables either take or receive arguments. 
An **argument** in C++ is the value that is passed to a function whenever that specific function is called.

Furthermore, a parameter is specified inside a parenthesis `()` right 
after the function name. We can add as many parameter values as we wish to inside a function.
## Syntax
To pass a parameter and/or argument values to a function, we use the following syntax:



  



void nameOfFunction(parameter1, parameter2)
{
  // block of code to be executed
}
intmain()
{ // calling the function
  nameOfFunction(argument1, argument2);
  return 0;
}

## Code example 
In the code below, we will create a function that takes a single parameter. Whenever we call the function, we pass an argument to the function.

#include <iostream>
#include <string>
using namespace std;

void myFunction(string myname) {
  cout << myname << " Onyejiaku\n";
}

int main() {
  // calling the function
  myFunction("Theophilus");
  myFunction("Chidalu");
  return 0;
}

## Code explanation 
* **Line 5**: We declare a function `myfunction` and pass a parameter `myname` to the function.
* **Line 6**: We create a code block to be executed whenever the function is called.
* **Line 10**: We call the function, and this time it passes the argument `"Theophilus"` to the function. 
* **Line 11**: We call the function again, and this time it passes the argument `"Chidalu"` to the function.  



How to pass parameters and arguments to a function in C++

Parameters in C++ functions are variables defined during function creation, while arguments are the values passed to these functions when called.
