Why Is Comparing if an Unsigned Int >= 0 a “Pointless Comparison”?

Question

I got warning:

Pe186 \"Pointless comparison of unsigned int with zero\"

when I tried to compile the following code:

Answer 1

You should remove = in

clLoop >= 0

Let's say your cpLoopStart is 5.

Then, clLoop value in the further iteratiosn would be -

clLoop = 4;
clLoop = 3;
clLoop = 2;
clLoop = 1;
clLoop = 0;
clLoop = 0;
clLoop = 0;
clLoop = 0;
