I am a CS student and working in c/c++ for 3 years. Though I am new here but I've worked on many c++ projects including simple tic tac toe,chess game, calculator for computing arithmetic operations like factorial, power, addition, multiplication on string inputs (even greater then limit if integer), graphical paint and many more. If you want I can send you sample files for the projects.
I'll work until your satisfaction. It will be my pleasure to help you. Looking forward for your positive response.
