using void functions

 

1.       Complete the program shown below. Note: do not omit the comments

 

a)       You will write a void function to get a positive integer between 1 and 12 inclusive.  The twelve numbers represent the months of the year.  The user will be asked to enter an integer between 1 and 12 inclusive.  If the number entered by the user is not within range, an appropriate error message will be displayed, and the user will be asked to try again until a valid number is entered.

 

b)       You will write a void function to print the month number and the month name with an appropriate message.  Consider a good layout when displaying the output.

 

c)       You will also complete the function main by making a call to the function GetMonthNumber with an appropriate argument and by making a call to the function DisplayMonth with an appropriate argument

 

d)       Add a loop to allow the program to repeat, allowing the user to continue.  Consider proper indentation and alignment of the statements.

 

e)       Output your name as well before the program ends.

 

f)        Test the functions using different test data.  Show several examples to show that the program performs validation check as well.  Write the documentation and include the screenshots.

 

g)       Submit the files to Moodles:   .cpp, .exe, and the Word document.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Answer 1

#include<iostream>  // for using cin and cout

using namespace std;

// function Protoype

void GetMonthNumber(int&);

void DisplayMonth(int);

    // Add a loop to allow the program to repeat

    while(1){

        int monthNum;               // a number respresenting a month

        GetMonthNumber(monthNum);   //get a month number

        DisplayMonth(monthNum);     // call function to output the month number

        // and month name

        

        system("pause");

    }
