Lab Objectives

1. Basic Input/Output Operations

2. Variables and Data types 3. Arithmetic Operations 4. Constants and Comments

Basic Input/Output Operations

We use the command cout<<”String” to display a message on the console for example:

cout<<"hello world"; We use the endl to start a new line

for next time cout<<"hello"<<endl; We can use \n to get same effect: cout<<"hello \n";

Basic Input/Output Operations

The operator << is used to concatenate data for output, for example to display the value of x and y each in a new line :

int x=5; int y=6; cout<<"The Value of x is "<< x

<< endl <<"and the value of y is "<<y<<endl;

Basic Input/Output Operations

On the other hand, to get input from user use the cin>>x command to receive input from user:

int x; cout<<”Please enter the value of

x”<<endl; cin>>x; As you notice the user should be

prompted to enter an input User Prompt
