Question

In this program, you'll create a program that utilizes an enumerated data type to manipulate the array.  

Here are the requirements:

Write a program that contains an enumerated data type named Letters.    In the declaration, include the following three enumerators: ALPHA, BETA, DELTA.

Then, create an array of integers three elements long. The array should be initialized to 0 using a 1-element initialization list.

Instead of using integers as subscripts, use the enumerators from your enumerated data type to assign the values 100, 40, and 75 to the first three elements, respectively.

Finally, print the contents of the array using a for loop that initializes the counter with an enumerator and uses an enumerator in the test expression.

Again, this will be structured as a guided multiple choice quiz where you will choose the appropriate code for a program. After you have gotten a perfect score, write out the program and compile and run it to see it in action.

Instructions:

Choose the correct C++ code for each requirement presented.

Sample Run:

100
40
75

Answer 1

• Below is the detailed implementation of the above problem in C++ with code and output shown.
• For better understanding please read the comments mentioned in the code.
• Using enums to define a user data type in which some values are defined while declaring the enum data-type, for example in the below program enum data type is used for iterating on array elements.
• CODE:

//include headers
#include<iostream>
using namespace std;

//defining a enum data type
enum Letters{
ALPHA, BETA, DELTA
};

//driver function
int main(){
  
//array of integers 3 element long initialized to 0 using a 1-element list
int arr[3]={0};
  
//using enumerators as subscript, assigning value to the array
arr[ALPHA]=100;
arr[BETA]=40;
arr[DELTA]=75;

//printing the contents of the array using enumerators as counters
for(int i=ALPHA;i<=DELTA;i++){
cout<<arr[i]<<endl;
}
  
return 0;
}

• OUTPUT:

100
40
75

• Below are the screenshot attached for the code and output for better clarity and understanding.
