Structure of the Problem Requirements
Enumeration is a user-defined type whose value is restricted to one of several explicitly named constants(enumerators). enum is the key word that is use for this. In this code first we declare global enum declaration, in which we have four values and then in main program we can make a instance of enum and then use it.
Source Code
#include <iostream>
using namespace std;
enum number { one = 1, two = 4, three = 9, four = 16};
int main() {
number n;
n = four;
cout<<"\n\n\t ****** Enumeration ******** \n\n";
cout << "Four Square : " << n << endl;
return 0;
}
