What are input and output streams in C++?
Input Stream: If the direction of flow of bytes is from the device(for example, Keyboard) to the main memory then this process is called input. Output Stream: If the direction of flow of bytes is opposite, i.e. from main memory to device( display screen ) then this process is called output.
How do you keep user from asking input in C++?
Get in the habit of using \n when you just want a new-line, and std::flush when/if you want to flush the stream. add a while loop in your function to continue input when wrong. You basically need a loop to keep asking the user to input new answer when length of input string is too long.

How do you ask for input in C++?

How do you take continuous input?
First you have to allocate space for the string you are reading, this is normally done with a char array with the size of a macro. char i[BUFFER_SIZE] Then you read data into your buffer, fgets might be better than scanf for that. Finally you check your exit case, a strcmp with “quit” .
