In many programming languages when you create a variable, you don't just give it a name but you must also say exactly what type of information is going to be stored in that variable. You must decide beforehand if it's going to store an integer, meaning a whole number without anything after the decimal point, or perhaps a floating-point number which might have a value after the decimal point or perhaps you need to store a single character, just one letter, or perhaps multiple characters, what's called a string, or is it a Boolean value, and that just means a value that can only be true or false, or it could be even more complex type of data, but you have to choose that data type.
Now of course, the point of making any variable is that we are going to use them, we are going to manipulate them, to ask questions of them, but that all begins by knowing how to make them.
