doubles printf in a recursive function?

[mugen]

Hi, in a project I use a recursive function and inside the function after a certain process I printf something but while running, the program writes it two times... I couldn't figure out the reason... Any help would be appreciated, thanks.

This is the code:

                printf("%f saniyede bulundu...",elapsed);
                printf("\n Continue to find higher value? y-n: ");
                scanf("%c",&chr);

You probably need to be aware that when you enter a response here you hit two keys: 'y' and 'enter-key', and therefore you get two inputs to this loop/recursion/whatever it is. If you want to ignore things like enter-key, you can do

scanf(" %c", &chr);

I think that worked thanks a lot I will make some tests to make sure though =)
