I'm writing this C calc and I wanted to do something like this: You get a possibility to select + or - or * or 2(power of 2). And then I started to write code that when you press 2, then you have posibillity to again select something. But this I cannot do(program doesn't give me any possibility and it just continue to printf). I've been looking over Internet but I cannot find anything about my problem. Red marked code is probably the problem
