Why wont my program work??

[jonobro]

I am working on a project which consists of reading input from a file called input.txt which has an infinite number of lines. Each line has a roman numeral, a space, a plus or minus, another space, and then another roman numeral. I am supposed to add the two numbers together and write the answer to another file called output.txt. However, the program is not working and I dont understand why. When I debug the program in visual studio, I just get a blank console and it does not say "press any key to continue". When I check my output file, it too is blank. Here is what I have...

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

void numeralstonumber(int&, int&, char&);
int calculateanswer(int, int, char);
void answertonumerals(int);

int main()
{
ifstream inputFile;
inputFile.open("input.txt");
while (!inputFile.eof())
{
    int number1 = 0;
    int number2 = 0;
    int answer = 0;
    char operator1;
    numeralstonumber(number1, number2, operator1);
    answer = calculateanswer(number1, number2, operator1);
    answertonumerals(answer);
}
inputFile.close();
}

void numeralstonumber(int &number1, int &number2, char &operator1)
{
ifstream inputFile1;
inputFile1.open("input.txt");
char numeral = ' ';
char nextnumeral;
while (numeral != '+' && numeral != '-')
{
    inputFile1 >> numeral;
    nextnumeral = cin.peek();
    if (nextnumeral == '-' || nextnumeral == '+')
    {
        nextnumeral = operator1;
    }
    else if (numeral == 'I' && (nextnumeral == 'X' || nextnumeral == 'V'))
    {
        number1 = number1 - 1;
    }
    else if (numeral = 'X' && (nextnumeral == 'L' || nextnumeral == 'C'))
    {
        number1 = number1 - 10;
    }
    else if (numeral == 'I')
    {
        number1 = number1 + 1;
    }

morning,

which has an infinite number of lines

That would take a very long time to process :)

When you debug it, have you stepped trough the program line by line? It shouldn't take too long.

I just get a blank console and it does not say "press any key to continue"

This implies that none of your if conditions are evaluating to true, and thefore it's stepping over everything. So yea, wack a breakpoint on line 34, then step line by line (F10 in VS).

Edit: You might be better reading each whole line into a std::string and parsing it like that. I'm not sure calling peek() is a good method to extract characters, but I might be wrong:
