Input of different data types using cin

Learning to input different data types using the standard console in object.

Learning Objectives

  • Usage of cin for different datatypes.
  • Multiple cin usage successively.
  • Forming cout chain with different data types.

Source Code

TC++ #1719


Source Code

Run Output

Enter a single character: R
Enter an integer: 123
Enter a float number: 345.56

You entered R, 123, 345.56

Code Understanding

char c; int n; float f;
Here we are declaring three different variables of different data types.

cout<<“Enter a single character: “; cin>>c;
Here we are collecting a char type input data. This is because the storage type of variable is char.

cout<<“Enter an integer: “; cin>>n;
Here we are collecting a integer type input data. This is because the storage type of variable is int.

cout<<“Enter a float number: “; cin>>f;
Here we are collecting a float type input data. This is because the storage type of variable is float.

cout<<endl<<“You entered ” <<c<<“, “<<n<<“, “<<f<<endl;
Here we are displaying all different types of data using the same cout chain formation.


  • cin can be used with different datatypes automatically without specifying the datatypes. This is an example of polymorphism or overloading of a method. In the same way you can also see polymorphic behaviour of cout also which can output different data types in the same formation.

Suggested Filename(s): inputmany.cpp, cin-char-int-float.cpp
