Snippet
Reading User Input with cin
The cin object reads user input from the keyboard. Use >> (stream extraction) for simple types like int and double. For strings with spaces, use std::getline() which reads an entire line until the Enter key is pressed.

1
std::getline(std::cin, name)

2
std::cin >> age;
Extracts an integer from input (stops at whitespace)
3
std::cin >> height;
Extracts a double from input for decimal numbers
