What is a computer program variable?
In programming, a variable is a value that can change, depending on conditions or on information passed to the program. Typically, a program consists of instruction s that tell the computer what to do and data that the program uses when it is running.
What is variable programming example?
Both ‘a’ and ‘b’ are variables. They are symbolic representations of any numbers. For example, the variable ‘a’ could contain the number 5 and the variable ‘b’ could contain the number 10. During execution of the program, the statement “a + b” is replaced by the Actual Values “5 + 10” and the result becomes 15.
