To all beginners. Not because it is a number, means it must be an "int"/"double"/"float" datatype.

Question

If you are dealing with a number,
and you can't decide whether you should declare it as an "integer"/"double"/"float" or a "string"/"char,"

Think of the usage of the number you are dealing with.

Are you going to subject/use it to a mathematical computation?

Like incrementing it or using it as part of a mathematical equation?
If yes, make it an "int"/"double"/"float"
(ex. age)

If you are just going to display or output it, then declare it as a "string"/"char"
(ex. House No., Tel. No., etc)
