Respuesta :
it's usually much easier to process a variety of items in an array than to process a large number of items that are kept in separate variables. (True)
What are variables?
The names you give to the locations in a computer's memory that are used to store values in a computer program are called variables. A variable is a symbol used to identify (or refer to) data. What information a variable contains is indicated by its name.
They are referred to as variables because the information represented by them is flexible but their operations are constant. A program should generally be written in "Symbolic" notation, which ensures that a statement is always true conceptually.
For illustration, let's say you want to store the values 10 and 20 in your program for use at a later time. Let's see what you'll do. The next three easy steps are as follows:
- Make up variables and give them meaningful names.
- Your values should be saved in those two variables.
- Use the variables' stored values by retrieving them.
