Which of the following is used to convert a number from one data type to another in visual studio?

Literal constant
Object
Convert class
Parser

The correct answer is C. Convert class.

A literal constant is a value that is stored directly in the code. An object is a variable that stores data. A parser is a program that converts text into a format that can be processed by a computer.

The Convert class is a class in the System.Convert namespace that provides methods for converting data from one type to another. For example, the Convert.ToInt32 method can be used to convert a string to an integer.

Here is an example of how to use the Convert class to convert a number from one data type to another:

int number = Convert.ToInt32("123");

This code will convert the string “123” to an integer and store the result in the variable number.
