Question

Give one example each of a variable and a constant in visual basic

Answer 1

An initial value is often assigned to a variable when it is declared, but this value may change many times during program execution. To declare a variable, you use the Dim statement (you can also use a variable without first having declared it, although this is discouraged)

Answer 2

final double a = 5.0; // constant

double b=3.0; // variable
