There's a question in my task that's confusing me

Hello

So I just started learning how code, currently learning C#. There's a question in my assignment that's confusing me. It goes like this: "Write a program, which creates both a typedef data type named date of original data type int and
an enumerated data type named Month, consisting of the 12 months with JANUARY starting at 1.
Next create a variable of data type date, with a starting value of 15, and a variable of data type
Month, with its initial value to be APRIL." If there's someone can help I would be very appreciated, would be awesome if you have time to provide some explaination under the code, but if you don't, that's ok too. This is what I just started doing:

#include<iostream>
#include<string>
using namespace std;

int main() 
{
    int Date;
    enum Month 
    {
        January = 1,
        February,
        March,
        April,
        May,
        June,
        July,
        August,
        September,
        October,
        November,
        December,
    };
}
