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.

// 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).

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

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

because inValid is *always* true.
