calling a decimal function

[Guppy25]

Ok, so i changed the "/" to a '/' but i can't get my calculate decimal function for work. I want to call a private function calculateDecimalValue() that computes a floating decimal of the fraction inside the enterFractionValue() function after the num and den are filled. I'm not understanding how to get it inside the enterFractionValue() function. I got the slash to work but the decimal in displayDecimal is just junk. Thanks again, Here's the code i have:

class Fraction
{
private:
double num, den;
double decimal;
static char slash;

void calculateDecimalValue(float decimal);

public:
void enterFractionValue();
void displayFraction();
static void displaySlash();

};
//implementation part-to be named-fraction.cpp
char Fraction::slash='/';

void Fraction::displaySlash()
{
cout<>num;
cin.ignore(80,'\n');
cout <<"The numerator is "<>den;
cin.ignore(80,'\n');

while (den == 0)
{
cout<<"Enter a number greater than zero."<>den;
cin.ignore(80,'\n');
}
cout <<"The denominator is "<>input;
cin.ignore(80,'\n');
while (input != 1 && input !=2)
{
cout<<"Your entry must be a 1 or a 2, please try again."<>input;
cin.ignore(80,'\n');
}
if (input == 1)

cout<<"The fraction in traditional form is "<
#include "fraction.h"
#include "fraction.cpp"
int main()
{
Fraction oneFraction;
oneFraction.enterFractionValue();
oneFraction.displayFraction();

cout << "Press Enter to continue";
getchar();
return 0;
}

You don't need a private function here. Also I don't think it's a good idea to make the numerator and denominator doubles. For one thing, they may not print out properly, i.e., you may have a fraction 3.0/4.0 where you really want 3/4.

Attached is a simple fraction program. (It really should be improved by reducing to lowest terms.)

You don't need a private function.. Here's a simple fraction class. I hope this works. The last time I tried attaching a file I didn't succeed.)
