An integer (more commonly called an int) is a number without a decimal point.
ex. any whole number. 74 69 69 63 22 -31

A float is a floating-point number, which means it is a number that has a decimal place. Floats are used when more precision is needed.
ex. 13.1415 77.9999 69.6969
a double has 2x the precision of float. In general a double has 15 to 16 decimal digits of precision, while float only has 7.

string is a sequence of characters. A string is noted by surrounding a group of letters with double quotes. Chars and strings are most often used with the keyboard methods, to display text to the screen, and to load images or files.
ex.
("dedpuol")
("BURP")
