How to Read and Print an Integer value in C++

The given task is to take an integer as input from the user and print print that integer in C++ language.

In below program, the syntax and procedures to take the integer as input from the user is shown in C++ language.

Steps:

1. The user enters an integer value when asked.
2. This value is taken from the user with the help of cin method. The cin method, in C++, reads the value from the console into the specified variable.

   Syntax:

   cin >> variableOfXType;
   
   where >> is the extraction operator
   and is used along with the object cin
   for reading inputs. The extraction operator 
   extracts the data from the object cin
   which is entered using the keyboard.
   

3. For an integer value, the X is replaced with type int. The syntax of cin method becomes as follows then:

   Syntax:

   cin >> variableOfIntType;
   

4. This entered value is now stored in the variableOfIntType.
5. Now to print this value, cout method is used. The cout method, in C++, prints the value passed as the parameter to it, on the console screen.

   Syntax:

   cout << variableOfXType;
   
   where << is the insertion operator.
   The data needed to be displayed on the screen 
   is inserted in the standard output stream (cout)
   using the insertion operator (<<).
   

6. For an integer value, the X is replaced with type int. The syntax of cout() method becomes as follows then:

   Syntax:

   cout << variableOfIntType;
   

7. Hence, the integer value is successfully read and printed.

Program:

Output:

Enter the integer: 10
Entered integer is: 10
