Read User input

We use standard std library from namespace iostream to handle IO streams.

We can read input from user using std::cin and store them in variables as shown below.

std::cout << "Enter your full name > ";
 
std::string name;
std::string surname;
 
std::cin >> name >> surname;
 
std::cout << "Your name is : " << name << " " << surname << std::endl;

When input is separated by space, it gets taken as multiple input and can be stored into variables using multiple >> direction operator.

If we need to read the whole line with spaces, we can use std::getline function.

std::cout << "Enter your full name > ";
 
std::string fullname;
 
std::getline(std::cin, fullname);
 
std::cout << fullname << std::endl;
