how we can get info from the user?(input)

Answer 1

there are several ways...
but first you need to know what do you want from the user?

you take a single variable like this

cin>>(variable name);

if you want to take multiple input then

cin>>(var 1)>>(var 2)>>..... (var n);

if you want to take a string inuput then you can use cin the same way as above
but there are some functions also, like
gets (var-name);
getline (var-name);
....etc

ther is a function that can also take input of any datarype
scanf ();
do a google search on it

as kain says...scanf () is a c function so you may not focus on learning it but you can use it in c++.

Answer 2

Mukul: scanf is C, not C++.
