Types of Variables in Rhomobile

Variable is a symbol or name that stands for a value. Variables play an important role in computer programming because they enable programmers to write flexible programs. Rather than entering data directly into a program, a programmer can use variables to represent the data. Later, when the program is executed, the variables are replaced with real data. This makes it possible for the same program to process different sets of data.

There are five types of variables supported in Rhomobile. These types of variables are explained below.
