Enum In C++ Programming

Enumeration ( Keyword of enum ) is a user defined data type in C++.It consisting of named values like elements, members, etc., that represent integral constants. It provides a way to define and group integral constants. It also makes the code easy to maintain and less complex. They using for the Switch case. The switch statement is c++ multi-way branch statement. It is used to take the place of long if-else chains, and make them more readable. However, unlike if statements, one may not use inequalities; each value must be concretely defined.

The program demonstrates the usage of an enumerated data type in C++. An enumerated type is a user-defined data type that consists of a set of named constants.

In this program, we define an enumeration type gender with two values, Male and Female.
The program then declares a variable g of type gender and initializes it with the Male value.
A switch statement is used to check the value of the g variable. If g has the value Male, the program outputs the string "Gender Male". If g has the value Female, the program outputs the string "Gender Female". If g has any other value, the program outputs "Invalid".
Finally, the main function returns 0 to indicate successful program execution.

Source Code

#include<iostream>
using namespace std;
//  ENUM in C++
 
enum gender {Male,Female};
int main()
{
    gender g=Male;
    switch(g)
    {
    case Male:
        cout<<"Gender Male";
        break;
    case Female:
        cout<<"Gender Female";
        break;
    default:
         cout<<" Invalid";
        break;
 
    }
    return 0;
}

Output

Gender Male
