They all end with an Output command. If not, is there any program that will remove it for me?
I don't think this tricks work with OS 2. This means that the calculator is waiting for a response from the user. Enter any number and press enter. The program then stores the number as N, and displays whatever you entered. For example:. The only problem with this is that if the person using your program doesn't know what your program does, he or she won't know what to do when the cursor pops up. To fix this, enter teh following:. Let's do one more example of this to show more about how variables and Input work together.
This program lets the user enter two numbers, finds the average of them, and displays it. This shows why you might want more than one variable in a program. These past two lessons have dealt with the two major concepts of a program: letting the user input information, and giving the user information. Now, it's time to do some interesting things with the information. At some time or another, most programs have to make a decision of some sort, doing one action under a certain condition, or another action under a different condition.
Try this program:. The point is to notice what happens when you put in an age bigger than 17, and what happens if you put in a smaller one. Here is what you should get when you run the program using different values for A:. See what the If statement on the third line does? What if you want more than one thing to happen if the condition is true, though?
Look at this example:. Now, what if you wanted to display something is the person is 18 or over, and display something different if they're younger than 18?
Notice that you still have to use Then and End if you use Else, even if you only want to have one command occur. The last thing to know about If statements is all the comparisons you can make. Below are some charts that list all the different comparisons you can make. Notice that you can make more than one comparison in a single If statement.
Loops are very useful statements that let you repeat a set of commands over and over without having to type them many times. For instance, say you wanted to make a program that displayed the numbers You could do it like this:. For loops let you repeat any number of statements a specified number of times. Here's what our counting program would look like with a For loop:. The second line looks pretty strange, doesn't it?
Here's what it does. First, it takes a variable F in this case , and makes it equal to 1, which is the second thing in the parentheses. Then the program continues until it hits an End statement. If F is smaller than the third number , the program loops back to the For statement and performs the commands inside the loop again. Otherwise, the loop ends. As another example, let's say you wanted to display all the even number from
