When do you use the getline?

Question

i have been watching videos on C++ and some ask for user input with

cin >> variable

and some use

getline (cin, variable)

Is there a difference and when woukd you uae one rather than the other.

Thank you.

Answer 1

getline => getting line: exp char* "my name is chokri"

=> cin getting first string: just "my" word.

Thanks.

Answer 2

getline gets the entire line, while cin only gets the letters/numbers up until it encounters a space or the line ends
