What is the purpose of a data type in programming?

Storing characters and numbers.

Defining variable names and values.

Deciding memory allocation and operations.

To specify variable size and value options.

How does a data type affect a variable's size in memory?

It specifies memory allocation based on value size and type.

Data types are unrelated to memory allocation.

It determines memory size before assigning a value.

Variable size is constant regardless of data type.

They determine the scope of a variable's value.

Data types are used for naming variables only.

They control memory allocation for each variable.

They define the size and type of values a variable can hold.

To perform arithmetic operations on variables.

To reduce the number of variables in a program.

To store values regardless of their type or size.

They ensure data integrity and optimize memory usage efficiently.
