Variable not initialized

[amglavin]

When I try to run my program this pops up: Run-Time Check Failure #3 - The variable 'quit' is being used without being initialized. I thought I initialized quit so I don't know how to fix this

    int quit; //Declaration

    while (quit != 1) { //First use 

So, where quit is initialized here

try int quit = 0;???? if its saying its not initialized then initialize it. maybe?
