Question

In C++ Write a function that has an integer as a parameter. (Be Original)

                                           The function will return a string that represents
                                            the day of the week. If the parameter is a 1,
                                            the function will return the string “Monday”.

                                            If the parameter is not between 1 and 7 the
                                            function should return "ERROR"

                                           Write a driver program to test your function.

                                            You are required to use a switch statement
                                            in your function. Use the default case to
                                            catch error conditions.

                                             NOTE:  for string variables use:

                                                           #include <string>
                                                           using namespace::std;
                                                            int main()
                                                           {

                                                                 string day; // day is a string variable
                                                                      …

                                                             }

#include <string>
#include <iostream>

using namespace ::std;

string get_weekday_string(int m) {
    switch (m) {
        case 1:
            return "Monday";
        case 2:
            return "Tuesday";
        case 3:
            return "Wednesday";
        case 4:
            return "Thursday";
        case 5:
            return "Friday";
        case 6:
            return "Saturday";
        case 7:
            return "Sunday";
        default:
            return "ERROR";
    }
}

int main() {
    string day; // day is a string variable
    int n;
    cout << "Enter a day value[1-7]: ";
    cin >> n;
    day = get_weekday_string(n);
    cout << day << endl;
    return 0;
