Re: Need a little guidance??

If x is less than or equal to 5, y is set to 1 -- otherwise y is set to 0; x is then incremented.

But better would be for you to ask, "I think that this statement does [...]. Is this correct?" Or at least provide a (minimal, but complete and compileable) snippet that shows the full context.

Is x incremented before or after the result of the comparison is assigned to y? Correct me if I am wrong in the explaination below.
y=x++<=5; is equivalent to y=(x++<=5);.
The part inside the brackets should be evaluated first. So doesn't that mean the binary comparison and the ++ should also be evaluated before the assignment?

Re: Need a little guidance??

So the error was this statement?
y=x++<=5; is equivalent to y=(x++<=5);.

This is the case of post incrementation so increment is done after the comparision.

Re: Need a little guidance??

I know that it is done after the comparison. I wanted to know if it was done after or before the assignment.

I'll go out on a limb a little (and search more later) and say that it is done after the comparison and before the assignment.
