Algorithms and Data Structures

In case of searched value is absent from array, we go through all elements. In average, complexity of such an algorithm is proportional to the length of the array. Situation changes significantly, when array is sorted. If we know it, random access capability can be utilized very efficiently to find searched value quick. Cost of searching algorithm reduces to binary logarithm of the array length. Compare. Public member function Compare strings Compares the value of the string object (or a substring) to the sequence of characters specified by its arguments.


C++ Notes: Algorithms: Binary Search. Divide in half A fast way to search a sorted array is to use a binary search.

The idea is to look at the element in the middle. Multi-Dimensional Arrays. This is another topic we get asked quite a bit. - How do I do a 2D/3D Array?

Multi-Dimensional Arrays

When I also started working with multi-dimensional arrays I found it hard to find the answers I wanted too. So I'll post up some info that will hopefully help other people. I'll go over both of the 2 major methods (Vector vs Pointer). Passing objects as function parameters - C++ Zygisx / ADS4 / overview – Bitbucket.
