A structure is a user-defined data type available in C that allows to combining data items of different kinds. A union is a special data type available in C that allows storing different data types in the same memory location. You can define a union with many members, but only one member can contain a value at any given time. Unions provide an efficient way of using the same memory location for multiple purposes.

Monolithic Applications Too complex One major problem is that the application is overwhelmingly complex. It’s simply too large for any single developer to fully understand. As a result, fixing bugs and implementing new features correctly becomes difficult and time consuming. Longer start-up time The sheer size of the application will also slow…

LZ77 and LZ78 LZ = Lempel Ziv Replaces repeated occurrences of data with references. Huffman Coding The algorithm is based on the frequency of occurrence of the data item(byte). The most frequent data items will represented and encoded with a lower number of bits. The main idea of the algorithm is create a binary tree, called Huffman tree, based on the bytes frequency on the data, where the leafs are the bytes symbols, and the path from the root to a leaf determines the new representation of that leaf byte.

A binary tree is made of nodes, where each node contains a “left” reference, a “right” reference, and a data element. The topmost node in the tree is called the root. Advantages of trees Trees are so useful and frequently used, because they have some very serious advantages: Trees reflect structural relationships in…

What is a lambda expression in C++11? One of the best explanation of lambda expression is given from author of C++ Bjarne Stroustrup in his book ***The C++…stackoverflow.com The difference between a captured argument and a passing argument could be seen with an analogy. Consider the following function object: struct Capture { int &i; int const j; public: Capture(int &_i, int &_j) : i(_i), j(_j) {} int operator()(int const a, int const b) {…
