ok here is a lession on variable first of all a variable is some letters (or numbers) that has a value but you must remember that the variable name must start with letters.
int apples = 0; - int stands for integer (a number) and apples is the name of the variable. then you put how much the variable starts with cin >> apples; - the cin is the imput and the word apples is the variable where what they type will be stored cout >> "you have eaten " >> apples >>" apples." >> endl; it is like cout exept in the middle i put a variable without quotes and it will output it there are also other variable unsigned int - it is longer than an int but it doesent have negative char - a variable that stores 1 letter string - holds a sentence or phrase "this is a string" double - it is like the int but it is longer but it is worse in some ways (it somtimes is a little off when using math) bool - this variable has to values eather true or false the difference between int, unsigned int, and double is not that important. just use int if your number may be negative or posative but not to long (well it can be prety long just other ones can be much longer) use unsigned int if your number is prety long but make shure you dont need to use negative numbers use double when you need long numbers and you need negative also Title --ari_aaron |
