Let us see how to generate different random numbers using C++. Here we are generating random numbers in range 0 to some value. (In this program the max value is 100).To perform this operation we are using the srand() function. This is in the C++ library. The function void srand(unsigned ... Read More

There are no ill-effects of allowing a pure virtual destructor in C++ program. It is must to provide a function body for pure virtual destructor as derived class’s destructor is called first before the base class destructor, so if we do not provide a function body, it will find out ... Read More
