    Question Program error

    Hi, i'm having trouble with the following very simple program, which converts miles to kilometers. When I try to exit out of the program entering C or c, the program still continues. Any help with this would be greatly appreciated. Here's the code:

    Code:
    // Miles to Kilometers conversion
    
    #include <iostream>
    
    using namespace std;
    
    float mtokm(int);
    
    int miles = 0;
    
    int main()
    {
    	
    	char keypress;
    	do
    	{
    		cout << "\n\nEnter the amount of miles you want converted to kilometers: ";
    		cin >> miles;
    		mtokm(miles);
    		(miles == 1 ? cout << "\n\n1 mile" : cout <<  "\n\n" << miles << " miles") << " is equal to " << mtokm(miles) << " kilometers.\n\n";
    		cout << "Press C to do another conversion, or any other key to quit: ";
    		cin >> keypress;
    	} 
    	while (keypress == 'c' || 'C');
    	
    		
    return 0;
    
    }
    
    float mtokm(int)
    
    	{
    		float kilometers;
    		kilometers = ::miles * 1.61;
    		return kilometers;
    	}
    Thanks in advance.

    thank you

    Thanks.. i had misstated what I meant, I meant to say when I try to exit with a different key the program still continues. But you knew what I meant. That fixed the problem, thanks again.
