One, what is a virtual function (if you do not know what the virtual function is, but have an urgent need to know, then you should start from here)Simply put, those member functions that are modified by the virtual keyword are virtual functions. The

The functions of dynamically allocating and freeing memory in C are malloc calloc and free, while in C + + the new new[] Delete delete[] is used to request dynamic space and free space.Note: new, new[], delete, and delete[] are operators, not

Do not use the size of the number, find the maximum value of two # include #include double Max (double A, double b) {Double q = sqrt ((a) * ( A-B); return ((A + c) + q)/2;} int main () {printf (5,8) Large number:%.0f\n, Max (5, 8));p rintf ("(0,4)

Set V is the object of a vector,If V is non-null, then v.at (0) and v[0] are indistinguishable, taking the first value in the array;If V is empty, then v.at (0) throws an exception (exception std::out_of_range), indicating that the array subscript

C + + polymorphic mode:(1) Static polymorphic (heavy, template)The type of the calling function is determined at compile time .(2) Dynamic polymorphism (overlay, virtual function implementation)At run time , determine which function is called and
