We just had a wonderful example of a binary search program in "Snippets" section of this forum, about two weeks ago.

Go to the main C forum, and you'll see the grey tab of "Snippets", click on it.

how to count comparison in binary search and interpolation search. is the number of comparison=number of iteration?or for binry search where we have two if conditions under the while loop ,the comparison will be 2*NUMBER OF ITERATION(one comparison for each if condition) or only one comparison for entering the while loop for once?

Every time the program makes a new guess at the answer, you should count one more comparison.

The number of if or else statements doesn't matter, unless a new guess is made, inside it.

In the binary loops I've seen, only one guess per iteration is made. Note that anyone could create a binary loop which made two guesses each iteration, but I have never seen that -- it's just a logical possibility.
