Unlike other languages – such as C and Delphi – VB lacks of the capability to increment and decrement a variable. Adding this feature, in the form of reusable Function

Suppose you create a vector and fill it with elements: vector MyVector;MyVector.reserve(20);for (int i=0 ; i tmp(MyVector);MyVector.swap(tmp); The vector temp has the same number of elements that MyVector has. By
One of the common sources for bugs and security risks is using a fixed size char array as a buffer for inputting data. For example: char buff[20];cout > buff; //
The standard C library declares the function calloc() in as follows: void *calloc(size_t elements, size_t sz); calloc() allocates space for an array of elements, each of which occupies sz bytes
Certain STL containers and algorithms require that you overload operator < for the class type they store as elements in order to sort and compare these elements. Note that STL
