How to keep the program from crashing from invalid input


Just use a simply do while loop. Get the user input and then check to see if the value is less than 0. If it's less than 0 renter the value.

Foolproof user input program using scanner

How do I get my program to separate not count the space between input as an integer?
Pass the two numbers in a single string. Find the space position and split the input in two parts, like in the example. NOTE: if you use c++11, the conversion to int can be made directly with std::stoi(str) string input; cin >> input; int spacePos, num1, num2; spacePos = input.find(" "); num1 = atoi(input.substr(0, spacePos - 1).c_str()); num2 = atoi(input.substr(spacePos + 1).c_
