We have been playing with strings and doing some basic operations on string for the last two posts. Another such interesting operation with strings is finding one string in another string. There are a number of things to be checked while searching for a string as a substring of second one. We shall be explaining these steps and other details in the proceeding lines. 

After a short break, we now continue our series on C++ object oriented programming. Inheritance in C++ has many real time applications. In this article I will be focusing on just one example where inheritance may be used in a C++ program: the database of a workplace organization. This example of inheritance in C++(part 1) is simple and will make clear to you many of the fine details needed to become a good programmer.

We saw how to match the two given strings last time and determine whether they first of them is less than, greater than or equal to the second string. We developed a simple string matching algorithm for that purpose. Similarly we also want to perform a number of other operations on our strings and need to find certain patterns and keys in them. Today we shall develop a simple character finding algorithm in a given string. Let us see which things we need to find out.

Since i started the series, I”ve covered a whole variety of topics ranging from the importance of classes, getters and setters and the various syntax and language complexities you guys need to know before delving into OOP seriously. Now we will get to topics which are a bit harder, and that starts off with inheritance in c .

Human Beings like to play with string in their daily life. We deal with all sorts of alphabets and words and often try to compare them with one another. To check whether we have two given set of characters equal or not, we make use of string matching algorithms. To match the two given strings, we use then to look for equality in both the strings for the desired results. A simple string matching algorithm is to iterate over each alphabet and match correspondingly. Let us see in detail how we do that.
