What's the prob with this code?

[Anonymous]

i wrote a small code to check if a real number is an integar or not...tried to use classes. Created three files-

----file 1---

include <cstdlib>

include <iostream>

include "RealNumberProp"

int main(int argc, char *argv[])
{
RealNumberProp number;
number.getValue();
number.displayValue;
system("PAUSE");
return EXIT_SUCCESS;
}

file2 ---RealNumberProp.cpp---

include <cstdlib>

include <iostream>

include "RealNumberProp"

int RealNumberProp::upperBound(double value)
{
return ceil(value);
}

int RealNumberProp::lowerbound(double value)
{
return floor(value);
}

bool RealNumberProp::isInteger(double value)
{
if((value==upperBound(value))&&(value==lowerBound(value)))
return true;
else
return false;
}

void RealNumberProp::getValue()
{
cout<<"Enter A Number";
cin>>mRealNumber;
}

void RealNumberProp::displayResult()
{
cout<<"The given number is a"<<isInteger(double mRealNumber)?cout<<"n Integer":cout<<" Non-Integar";
}

file 3-----RealNumberProp.h

include <cstdlib>

include <iostream>

include <math>

class RealNumberProp
{
private:
double mRealNumber(0);
int upperBound(double);
int lowerbound(double);
bool isInteger;
public:
void getValue;
void displayResult;
}

NOW, WHEN I COMPILE THIS, i get an error:- RealNumberProp : No Such fiel or directory...

three of these files are placed under the same directory..what's the problem then...? m using dev c++...

Ok just keep trying ;o)

I'm not a C++ GURU but my advice is go slowly and be carreful what you write !

I'm will do not talk about your strategy to reach the goal, it's not the subject !
Here the code I can compile and run with devcpp : Hope this help ;o)
