using enum indexed array
I'm attempting a program with an array indexed by and enum. I will need user input to determine which part of the multiple dimensioned array to use. My problem is I can not figure out what to use to grab the user input. We have not covered maps and pointers yet and the instructor indicated we will need to use the #cctype header. For the life of me I can not make the connection here. I feel if I just had an idea of how to grab the input I could finish the rest of the program alone. Any help would be greatly appreciated. I have other snippets of code for other functions but this is the snippet that applies to my question.
//preprocessor commands
# include <iostream>
# include <iomanip>
# include <cctype>
# include <cstring>
using namespace std;
//Const Variables declared
const int NUM_OF_ROWS=4;
const int NUM_OF_COLUMNS=4;
enum curFrom{USD,INR,GBP,EUR};
double const conversionTable[NUM_OF_ROWS][NUM_OF_COLUMNS]={{1.00,66.60,0.89,0.65},
{.015,1.0,0.014,0.010},
{1.55,99.42,1.35,1.0},
{1.12,73.70,1.0,0.74}};
double currency;
int main()
{
cout<<"Please enter the currency to convert from.";
}

Here's an article I wrote about the proper way to handle user input:

Thank you. I understand the part about getline from input. We have not been introduced to sstream yet so I'm not sure how to make the while loop stop. I see from the article that you use it to assign the input to line to stop the loop. However, it's not something I can use yet. I'm not sure what to set as the loop control once I get the enum value from the user. Does that make sense? I've been fiddling with this assignment for days and I am not sure if I make sense anymore. Also, your article was excellent and clearly stated esp for a beginner like myself.
Don't be afraid to use something you haven't learned about. Unless your professor is a bad teacher and specifically forbids it, go ahead and use the information you learn on your own.
My fear is that he may think that I've "stolen" the code. However, if I understand it I would hope that would not be the case. Thank you,again, for your help.
