QBasic Breeze Ascendancy

Boolean argumentation is the argumentation of things getting true or false. In programing this argumentation is acclimated to ascendancy what a program does. In adjustment for the computer to absitively if something is true or not, it haveto be declared in algebraic terms. You cannot say Is it six oclock, you accept ask if time = 6.00. The comparisons acclimated in qbasic are according (=), beneath than (<), greater than (>), beneath than or according to (=<), greater than or according to (>=) and not according (<>). Also, to hotlink calm added than one comparison, there are analytic operators. These are AND, OR and XOR. We will awning absolutely what these beggarly after on, but you apparently accept the first two already.
One of the alotof advantageous statements in QBasic is the IF statement. It allows you to accept what your program will do depending on the altitude you accord it. The next few programs will be demography a attending at means to use the IF statment.
CLS
num = INT(RND Ascribe Aces a amount amid 1 and 100: , answer
IF num = acknowledgment Then Book You win
IF num > acknowledgment Then Book Too Small
IF num < acknowledgment Then Book Too big
12IF.BAS shows the alotof basal use of the IF...THEN statement. The architecture is
IF [conditional] Then [do this]
In this program the conditionals analysis what the assumption is about to answer. One ancillary note, this program does not accept RANDOMIZE TIMER intentionally, this will acquiesce you to play the bold and accumulate accepting afterpiece to the number, the check is that already you acquisition the number, the bold has no epitomize value. We will create a bigger adaptation a little after though.
CLS
num = INT(RND Ascribe Aces a amount amid 1 and 50: , answer
IF acknowledgment = num Then Book You Win Abroad Book You Lose
This adaptation of the IF account adds the the Abroad operator. The Abroad abettor allows you specifiy what happens if the codicillary fails.
IF [conditional] Then [do this 1] Abroad [do this 2]
So, if the codicillary is true do this 1 will appear if the codicillary is not true do this 2 will happen.
