#define cpp cout << "C++" << endl;

#define is used for creating names that will overwrite the current event.

For example:

// we are going to make a program that will use a #define for replacing a number
#include <iostream>
#include <cmath>
#define FIVE 5
using namespace std;
int main() {
   cout << "The normal square root of 5 is: " << sqrt(FIVE) << endl;
   cout << "The int square root of 5 is: " << (int)sqrt(FIVE) << endl;
   return 0;
