C++ User Input You have already learned that cout is used to output (print) values. Now we will use cin to get user input. cin is a predefined variable that reads data from the keyboard with the extraction operator (>>).…
There come situations in real life when we need to make some decisions and based on these decisions, we decide what should we do next. Similar situations arise in programming also where we need to make some decisions and based…
