Enumerated Types: Creating Named Constants

An enum creates a custom data type with named integer constants. By default, the first value is 0, but you can assign specific values. Enums make code more readable by replacing magic numbers with descriptive names.

cpp

#include <iostream>
using namespace std;
 
enum Difficulty { EASY, MEDIUM, HARD };
 
int main() {
    Difficulty level = MEDIUM;
    
    if (level == EASY) {
        cout << "Easy mode" << endl;
    }
    
    return 0;
}

Breakdown

enum Difficulty { EASY, MEDIUM, HARD };

Creates a new type where EASY=0, MEDIUM=1, HARD=2

Difficulty level = MEDIUM;

Declares a variable of the enum type
