Loop/bool

Can anyone help me fix this problem I have in my program it keeps displaying the same cout statement no matter what output.

Code:

// InvalidBinDr.cpp 

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

// FILL IN InvalidBin PROTOTYPE: 

 
int main()
{
	// Variables local to main
	bool inValid=true;	// True if an invalid binary # is entered
	string input;// The user entered string

while (true) {
    cout << "Enter a binary number (8 digits or less): ";
    getline(cin, input);
    if (input.size() <= 8) break;
    cerr << "You entered more than 8 digits.  Please re-enter your number." << endl;
}



	if(inValid)
		cout << input << " is not a binary number." << endl;
	else
		cout << input << " is a binary number." << endl;



	return 0;
}

// FUNCTION InvalidBin RETURNS TRUE IF THE STRING ENTERED BY THE
// USER DOES NOT REPRESENT A VALID 8-BIT BINARY NUMBER OTHERWISE
// IT RETURNS FALSE, (i.e. the string has 8 bits that are 1's or 
// 0's only).

anyone?

need some help Bool and loops

How To Ask Questions The Smart Way
Questions are answered when we get around to answering them, not by you demanding every few minutes for special attention.

You never modify the value of inValid. You set it to true at the top of the file and then later test it with an if(). Your code will *always* execute

Code:

cout << input << " is not a binary number." << endl;

because inValid is *always* true.
