Need Help Troubleshooting Program in C - c

Question

I need this program to stop asking for flavors when the word "lemon" is said. For some reason, I can't get it to work correctly. I have tried to add an "if" statement for it but it wasn't working out correctly. The code will stop asking for flavor for a split sentence and then will start asking for it again and it will go all the way to 15 flavors instead of stopping at the flavor "lemon".
