Constants They are variable whose values will not be changed by the program. What are the advantages of having constants? - Improves the readability of code - Easier to update the programming code if the value changes - Reduce the likelihood of inconsistency causing errors if multiple places use the same value instead of using the same constant. Concatenation It is the joining of character strings end to end. For Example: "Hello, " "world" could equal "Hello, world" Split() For E...
