What does cin mean? As well as what it means

Answer 1

It's made to take in User values from the console or where ever the program that makes a call to cin is. It can be stored in variables and used for purposes the program need. cout is the opposite, where it prints to the screen. And it stands for C- input. It comes from it's superset, C. Where C calls for a FILE* stdin (or standard-input), cin calls to the same. cout would mean C-output, where C calls for FILE* stdout (or standard-output), cout calls to the same.
