Can you explain what is meant by data types for variables in programming?

Data types for variables in programming define what kind of values a variable can store and what operations are permissible on those values.

For example, in C# there are several main types:

• int — integers
• double — floating-point numbers
• string — text strings
• bool — logical values (true/false)

The data type helps the compiler and the program understand how exactly to use the variable, how much memory to allocate, and what operations are allowed.

Example:

int age = 30;
bool isActive = true;
string name = "Ivan";

Here, the variable age can only store integers, isActive — a boolean value, and name — text.
