Chapter 7, Problem 1MC

The memory that is allocated for a_______ variable is the actual location that will hold any value that is assigned to that variable.

1. a. reference type
2. b. general type
3. c. value type
4. d. framework type

Program Description Answer

The allocated memory for value type variable is the actual space that will store any value which is allocated to that variable.

Hence, the correct answer is option “C”.

Explanation of Solution

Data types in C#:

In C# and .NET framework, all data types fall into two types. They are as follows:

• • Value types
• • Reference types

In C#, the data types such as int, double, decimal, and bool are used. In addition to these, C# mainly focuses on value types and reference type.

Value type:

Value type is a one type of data type which holds the actual value of variables.

• • The variables are stored in memory allocated for variables in stack.
• • The memory allocated for value type is the actual location which holds the value assigned for the variable.

For example:

int a=20;

• • Here, the value “20” is stored in memory space which is allocated for the integer variable “a”.

Explanation for incorrect options:

Reference type:

Reference type works different from value type. It does not store its value directly, instead it stores the memory address where the value is being stored.

Hence, the option “A” is wrong.

General type:

It is not used to hold the actual address location of variable.

Hence, the option “B” is wrong.

Framework type:

It is not used to hold the actual address location of variable.

Hence, the option “D” is wrong.
