My question is what does the perform change do in this code and do I need to run this through some program in order to solve?



start
a = 2
b = 4
c = 10
while c > 6
perform changeBAndC ()
endwhile
if a = 2 then
perform changeAAndB ()
endif
if c = 10 then
perform changeAAndB ()
else
perform changeBAndC ()
endif
print a, b, c
stop

changeBAndC ()
b = b + 1
c = c - 1
return

changeAAndB ()
a = a + 1
b = b - 1
return

It's not going to do anything, as you didn't pass any values into it. So the when it changes A & B, it's only going to change it to the local variables. You would need to pass them back, or declare them as global variables.

Since you've only posted a narrative as to what the code is doing, I can only take a guess. If you can provide us with much more detailed code, then we can get a better idea to answer your question.

This is all the code I got I was just wondering what the perform change means and my other question is what program I can use to try to enter in code and it will tell me any errors I may have.

Well, that isn't correct C/C++ code by any stretch of the imagination.
