Question

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. Use a switch statement. 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 Display Month with an appropriate argument d) 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.

this question is based on C++ programming

Answer 1

// do comment if any problem arises

// code]Using ONLY the following header functions:

#include <iostream>

using namespace std;

void GetMonthNumber(int &month)

{

    // read month

    cout << "Enter an integer between 1 and 12: ";

    cin >> month;

    // invalid month

    while (month < 1 || month > 12)

    {

        cout << "Invalid integer!\n";

        cout << "Enter an integer between 1 and 12: ";

        cin >> month;

    }

}

// b) You will write a void function to print the

void Display_Month(int month)

{

    cout << "\nMonth number: " << month;

    cout << "\nMonth name: ";

    // month number and the month name with an appropriate message.

    // Use a switch statement.

    switch (month)

    {

    case 1:

        cout << "January\n";

        break;

    case 2:

        cout << "February\n";

        break;

    case 3:

        cout << "March\n";

        break;

    case 4:

        cout << "April\n";

        break;

    case 5:

        cout << "May\n";

        break;

    case 6:

        cout << "June\n";

        break;

    case 7:

        cout << "July\n";

        break;

    case 8:

        cout << "August\n";

        break;

    case 9:

        cout << "September\n";

        break;

    case 10:

        cout << "Octuber\n";

        break;

    case 11:

        cout << "November\n";

        break;

    case 12:

        cout << "December\n";

        break;

    default:

        break;

    }

}

int main(int argc, char const *argv[])

{

    // call to the function GetMonthNumber with an appropriate argument

    int month;

    GetMonthNumber(month);

    // and by making a call to the function Display Month with an appropriate argument

    Display_Month(month);

    return 0;

}

Output:

Enter an integer between 1 and 12: 0 Invalid integer! Enter an integer between 1 and 12: 13 Invalid integer! Enter an integer between 1 and 12: -5 Invalid integer! Enter an integer between 1 and 12: 1 Month number: 1 Month name: January DS D.lvons
