Common Programming Concepts

Variables:

• Variables are immutable by default. Can be made mutable by writing mut keyword before variable name.
• Constants are declared using const keyword. For every const declaration data type must be specified.
• For naming conventions, const variable names must be in uppercase with _ in between for multi word.
