Answer 2

Answer:

Variables

A variable is a symbolic name for (or reference to) information. The variable's name represents what information the variable contains. They are called variables because the represented information can change but the operations on the variable remain the same. In general, a program should be written with "Symbolic" notation, such that a statement is always true symbolically. For example if I want to know the average of two grades, We can write "average = (grade_1 + grade_2) / 2.0;" and the variable average will then contain the average grade regardless of the scores stored in the variables, grade_1 and grade_2.

Explanation:

Variables - Symbolic Nature

Variables in a computer program are analogous to "Buckets" or "Envelopes" where information can be maintained and referenced. On the outside of the bucket is a name. When referring to the bucket, we use the name of the bucket, not the data stored in the bucket.

Variables are "Symbolic Names". This means the variable "stands in" for any possible values. This is similar to mathematics, where it is always true that if given two positive numbers (lets use the symbols 'a' and 'b' to represent them):
