Data Types in C and C++

Data types specify the type of value that a variable can store. C and C++ provide several built-in data types.

Common Data Types

Data Type	Purpose
int	Stores integer values
float	Stores decimal values
double	Stores larger precision decimal values
char	Stores a single character
bool	Stores true or false values in C++

Example

int marks = 85;
float temperature = 36.5;
char grade = A;
double salary = 45000.75;

Choosing the appropriate data type helps programs use memory efficiently and represent data correctly.
