cpp:define

#define

#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;
}
