I don't understand com 100%

Question

I still don't understand how to properly use cin. Its for input. But what does it mean to input. Like input num1 or num 2 I don't know what that does

Answer 1

cin is the console input which is used to take input from user
cout is console output which is used to show the input number at console ex:-
#include <iostream>
int main() {
int a,b;
std::cin>>a>>b;//input
std::cout<<a*b;//output shows at console
return 0;
}

Answer 2

cin assigns your input as a value to given variable

cin simply means (Console In) its reads input stream from your keyboard

Using GAWEN STEASY sample you can see that she has 2 variables that need input from keyboard(cin), once there value has been assigned these 2 variables are then multiplied together and displayed to console 👍

Answer 3

cin is an object of class istream. It is used to accept the input from the standard input device

Answer 4

you can assign by
int a;
a = 5;
see variable a is assigned with value 5.
its proper way to assign
u can assign value like this also
int a = 5;

cin basically console input (cin)
its mean something coming from keyboard
by using cin, we make options for user that they can put their choice

here is a code in which 2 variables are given
a and length
