While working with classes, we often want to have the user defined functionalities which help enormously during the rest of the program. When we deal a lot with arrays, we often want to add the contents of two arrays into a single larger array. This could tediously be done by declaring another array of the combined size of the two and adding them one by one in it. The better option to do this is to overload the addition operator ( ) once which saves us doing this process repeatedly if we add two arrays time and again in our program. Let us see how we can do that efficiently.

There are many ways provided by the C language to store information. The most basic of them are variables of multiple types i.e. int, float, char etc. But when we require storing the information of a lot of such variables, the language has provided us a facility of arrays. Arrays are the most basic means of storing very large amount of data, and the sildenafil vs viagra language allows us the facility to manipulate the data in those arrays in any way we like. But arrays are static and if we need to allocate data on the run time, we use dynamic arrays to store space and allocate memory on the system as per our use. Dynamic arrays are helpful in many scenarios in this language, but sometimes the management of these dynamic arrays can turn to be an issue. There is one more way that C language allows to store information through, the use of Linked Lists.
Deviating a little from our series of discussion on Sorting Algorithms, this time and maybe the next one too, we would be plunging into certain other core concepts considered vital and important to good programming. Last time, we carried out the Selection Sort using the recursive technique. As recursion is a tricky and fundamental topic and a very powerful tool as well, we would be having some more discussion on recursion now.
Working in C++ is considered relatively difficult because the programmer is faced with many additional headaches; biggest of them being the memory management and the consequent pointer hazards. The allocation and de-allocation of memory at the appropriate time is not an easy job. But this very feature makes C++ one of the fastest and efficient Programming Languages. Pointers are used to access the memory blocks in C++. I assume that you are already familiar with the pointers. So I shall explain some of the dangers you might be in while working with pointers. Then gradually we shall advance towards more advanced usage and hazards.
