Post subject:  Just learning C, I have a rookie question

So to learn C I set a goal that I thought was realistic and tried to write the code to make it happen.

My first goal is to simply make a counter on the display. I want to get it to count from 0 to 200 then stop. "tall" is just a random name I picked. I noticed in robotc that "tall" is in black text not colored. I know the code as it is will not work, it gives me a "Procedure call Parameter" error for the displayLCDCenteredString line of code. Any help for this would be great. Thanks in advance. Jay

task main ()
int tall = 0;

while ( tall < 200)

bLCDBacklight = true;
displayLCDCenteredString(0,tall); //How to I display the value of "tall" in the display

tall ++;

And by the way, next time add
around your code to make it more readable ;)
What you need to do for `displayLCDCenteredString` is use something like this:
displayLCDCenteredString(0, "%f", tall);

Does that work?
See this page for further reference.
Do note that in everyday programming, the use of ellipses is quite rare, and it's considered "evil" by many :) But "printf" is a pretty standard function.
