how do you square a number?

[Tricia]

Write a program to output a table of values of the integers starting at 1 and their squares. Label the table at the top of the columns.

this came right out of one of the ruing textbooks and i wrote a code but it won't run though...what am i doing wrong?

code:

setscreen ("graphics:640;480") var sum : string for count : 1 .. 5     put "Number     Square"     put count, sum     sum := count * count end for

you might think i'm kind of stupid not to know this but i love computer programming and i am just not good at loops

try swapping your second-last and third last line

[Tricia]

i tried it's not working it seems that there was something wrong with my second count...on the sum := count * count part

In case that's ambiguous, he meant:

code:

setscreen ("graphics:640;480") var sum : string for count : 1 .. 5     put "Number     Square"     sum := count * count     put count, sum end for

Tricia, are you familiar with writing functions?

[Tricia]

um...i did do what bugzpodder was saying to me...but it's still not working it highlights the second count i put in

and honestly i am not all that expert in functions

[Tricia]

can anyone help me please?

Well, I'm just guessing, but I think you want the header:

code:

put "Number     Square"

To only be printed once. As it is, it gets printed each time the loop repeats.

[Tricia]

i already know how to do the header but i also need to have numbers and square them. in the book it says....it should look lyk this

Number Square
1 1
2 4
3 9
4 16
5 25

so what code should i put in?

[Tricia]

except the squared numbers should be under the square heading

[wtd]

You could use tabs rather than spaces.

code:

setscreen ("graphics:640;480") var sum : int put "Number\tSquare" for count : 1 .. 5     sum := count * count     put count, "\t\t", sum end for

Try that.

[Tricia]

thanks it worked this time

[wtd]

You're welcome.

Now, the real question is, do you understand why it works?

[Tricia]

yup...my main mistake was putting the put statement under the for statement it messes up my whole program

[wtd]

Good. It's better to fail and know why than to succeed and think it's magic.

I thought it was because in the original code, it was

code:

var sum : string

and then you tried to assign an integer value to a string. That's why it was wrong?
