i am having problems making my program works. the following is what I have to do and underneath it is my program which I cant get it to work. i am not sure what my problem is. if you can figure it out that would be great thanks!!   Write a C++ program that takes a date in the following format: December 24th, 2021 and extracts the day, month, and year as 3 integers. Your program should have and use at least the following functions: (a) Write a function getDate that prompts a user to enter a date as a string and returns it. (b) Write a function extract that takes as its parameter a date and returns the day, month, and year as 3 integers. (Hint: you can use the function isdigit(c) that returns true if c is a digit character and false otherwise.) (c) Write a function convertDigits that takes as its parameter a string of digits and converts it to an int.

i am having problems making my program works. the following is what I have to do and underneath it is my program which I cant get it to work. i am not sure what my problem is. if you can figure it out that would be great thanks!!

 

Write a C++ program that takes a date in the following format: December 24th, 2021 and extracts the day, month, and year as 3 integers. Your program should have and use at least the following functions:

(a) Write a function getDate that prompts a user to enter a date as a string and returns it.

(b) Write a function extract that takes as its parameter a date and returns the day, month, and year as 3 integers. (Hint: you can use the function isdigit(c) that returns true if c is a digit character and false otherwise.)

(c) Write a function convertDigits that takes as its parameter a string of digits and converts it to an int. (Hint: to convert a digit character to a digit number use static cast (’d’) - static cast(’0’) where d is 0, 1, ..., 9)

(d) Write a function convertMonths that takes as its parameter a month as a string and returns a corresponding number from 1 to 12 (1 for January, . . . , 12 for December). 

Write a program that repeatedly prompts the user to enter the date in the previous format.
The program should then output it as in the examples below.
For example,
Enter a date -- December 24th, 2021
24/12/2021
Try again (Y/N) -- Y
Enter a date -- February 28th, 2021
28/2/2021
Try again (Y/N) -- Y
Enter a date -- February 2nd, 2021
2/2/2021
Try again (Y/N) -- N

 

This is my program:

#include <iostream>
#include <string>

//Function prototypes
  void getDate();
  void extractDate(int&);
  int convertDigits(string);
  void convertMonth(string, int&);

  int main(){

    string date;
    int day, month, year;
      date = getDate();
      cout << " " << day << "/" << month << "" << year << "\n";
    return 0;
  }

 void getDate()
 {
   string date;
    cout << "Enter any date -- ";
    getline(cin,date);
    extractDate(date);
  return date;
}

  void extractDate(int& date)
{
  int y, z;
  string mdn

    y = date.find(" ");
    mdn = date.subtr(0, y);
    convertMonth(mdn, month);

    z = date.find(" ", y+1);
    mdn = date.substr(y+1, z-3);
    day = convertDigits(mdn);

    mdn = date.substr(y+1, date.length());
    year = convertDigits(mdn);

  }

  int convertDigits(string myDate)
  {
    int n;
    int sum = 0;
    n = pow(10, myDate.length()-1);
    for (int i = 0; i<myDate.length(); i++)
    {
        sum = sum+(myDate[i]-48)*n;
        n=n/10;
    }
    return sum;
  }

  void convertMonth(string month, int& Num)
  {
    if (month == January){
      Num = 1;
    }
    else if(month == February){
      Num = 2;
    }
    else if (month == March){
      Num = 3;
    }
    else if (month == April){
      Num = 4;
    }
    else if (month == May){
      Num = 5;
    }
    else if (month == June){
      Num = 6;
    }
    else if (month == July){
      Num = 7;
    }
    else if (month == August){
      Num = 8;
    }
    else if (month == September){
      Num = 9;
    }
    else if (month == October){
      Num = 10;
    }
    else if (month == November){
      Num = 11;
    }
    else if (month == december){
      Num = 12;
    }
    else{
      cout << "invalid \n";
    }
  }
