Data Types

Experiment 2

Aim: To examine and verify different data types of CPP.

Theory

Data types are essential in programming, defining the kind of data that can be stored and used within a program.

Data Types:

Primitive data types are the most basic, built-in types provided by programming languages for storing simple values.

1. Integer (int): Whole number

Example: int a = 77;

2. Float: A single-precision floating-point number.

Example: float x = 3.9;

3. Double: A double-precision floating-point number.

Example: double a = 3.444555;

4. Char: Represents a single character.

Example: char initial = 'L';

5. Boolean: Represents true or false values.

Example: bool isStudent = true;

6. String Types:

String: Represents a sequence of characters. Example: string name = "Harison";

Algorithm

• Begin

• Include the Necessary Headers

• Include the header files <string> and <iostream> for string and I/O operations. Use the standard namespace.

• Declare variables of various data types: int, float, char, bool, string, and double.

• Input and Output Operations

• For each variable:

  • Prompt the user to enter a value.
  • Read the input value.
  • Output the size of the variable using the sizeof operator.

• End
