I made a for loop for searching and sorting in the header file. Both loops start off like this:

for (int i = 0; i < n ; i++)

find.c compiles fine for me but when I put the needle at the end of the array, it doesn't work. But it works fine if the needle is at the top or in the middle of a sorted or unsorted array. Can someone please lead me to the right direction?

Thank you.

    test your search and sort functions separately, if you are using binary search, then what condition have you placed 'values[mid] == value' to get the exact element, if yes then try 'values[mid] == value || values[mid+1] == value'.

Without seeing your code, my guess would be that your for loop is stopping 1 short of actually evaluating the last item. You could change your middle parameter of your for loop to: i <= n to test for this possibility.

  • My guess would be that doing this will most likely induce a segfault (out of bounds access) =P
