Lesson 8: The cin statement

NOTE: for a fast copy, follow these steps in order:

Click anywhere in a text box below (result will be a blinking vertical line in the text box)
Hit ctrl + A on the key board (the "ctrl + A" means hit Ctrl and A at the same time)
(The result should be that all the text inside the text box lights up in blue)
Hit Ctrl + C (Nothing significantly happens that is visible) and now its copied to the clipboard and your ready to paste it anywhere 

you wish



The cin statement


The cin statement allows the user to enter a value for x in this example
#include <iostream>
using namespace std;

int main()
{
 int x=6;
 cout << "Enter an integer value: ";
 cin >> x;
 cout << "you have entered " << x << endl;
 system("pause");
 return 0;
}

notice that the cin.get() statement is replaced by the system("pause") because the cin.get() will not work once cin has been called. (i 

don't know why that is the case)

Here is another example. Computers don't like to divide by zero, you can try to input 0 for y to see what happens or you can also find 

out what happens by watching the video.
#include <iostream>
using namespace std;

int main()
{
 int x;
 int y;
 cout << "Enter a dividend: ";
 cin >> x;
 cout << "Enter a divisor: ";
 cin >> y;
 cout << "The quotient is " << x/y << " with a remainder of " << x%y << endl;
 system("pause");
 return 0;
}
