I have a code with 3 columns. The 2nd. columns should contain a single character that shows if the numbers in the 1st. column is increasing or decreasing.
In other words, if row 2 is greater than row 1 in column 1 then put an "D" else put in an "I".

I guess I sort of get what your trying to say, but not entirely.
When you say "put", are you writing to a variable, saving to a file, printing to the console, etc?
And when you say that you have code with three columns, do you mean you have multi-dimensional array?
My code creates an output file and from the fprintf option. A variable is created to form another column that column is supposed to look at the prior column and put a single character (I) in that column if the row below is greater than the row above else if lesser put a "D" character.
Hope that helps.
Keep the previous value around somewhere. if newvalue > oldvalue print I else print D. Then change oldvalue to newvalue and get a new newvalue from the table.
Thank you for responding. That is exactly what I am trying to do but I do not know the code to use....
Does anyone know what code to use?
You are aware that "if" and "else" are C keywords?Originally Posted by youngdawny
Yes - I am aware of "if" and "else". The problem I have is how to read the line and to check which of the tw rows is greater and use the character "I" or "D".
And what's wrong with
?Code:if (lastrow < thisrow) printf("I"); else printf("D");
