    How do i change the input?

    #include <iostream.h>
    #include <conio.h>
    int main()
    	double meannumbers;
    	double totalmeannumbers = 0;
    	double totalamountofnumbers = 0;
    	double holder=100;
    	double lowest;
    	cout << "Enter your first test score\n" <<endl;
    	holder = meannumbers;
    	while (meannumbers !=-1)
    		totalmeannumbers = totalmeannumbers + meannumbers;
    		totalamountofnumbers ++;
    		cout << "Enter your next test score or enter -1 to quit."<<endl;
    		cin >> meannumbers;
    		if (meannumbers <= holder && meannumbers >=0)
    			holder = meannumbers;
    	cout<< "The average of the numbers is " << (totalmeannumbers-holder)/(totalamountofnumbers-1);
    	return 0;
    i wanna make the input as "q" instead of "-1". When i do while (meannumbers !='q'), it just leads me to an infinite loop? BTW this code works perfectly i just wanna change the terminating input to q instead of -1

    Read into a string instead, then parse the string into a double if it is not equal to "q". You may need to rework your current loop logic a little too.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.
