1H - Programming Assignment

Now you know how to use variables and change their value. Ready for your first programming assignment?

But there's one small problem: you haven't yet learned how to display data to the screen! How are you going to know whether or not the program works if you can't see any output?

So, here's a VERY brief rundown of the next few lessons. To display data, use:
writeln (argument_list);
Argument list is composed of either strings or variable names separated by commas. An example is:
writeln ('Sum = ', sum);

Here's the programming assignment for Chapter 1:

Find the sum and average of five integers. The average should be real. The five numbers are:
45 7 68 2 34
Use a constant to signify the number of integers handled by the program -- define some constant as having the value 5.

The output should look something like this:

      Number of integers = 5
      Number1 = 45
      Number2 = 7
      Number3 = 68
      Number4 = 2
      Number5 = 34
      Sum = 156
      Average =  3.1200000000E+01

As you can see, the default output method for real numbers is scientific notation. The next section will tell you how to format it to fixed-point decimal.
