Main function –This function marks the start of any C program. It is a preset function that is first executed when a program is run. The main function may call other functions to execute specific tasks. Example: int main(void) { // code to be executed return 0; } ...
friend return_type class_name::function_name (arguments); // for a member function of another class class intellipaat{ friend int intellipaat_Function(paat); statements; }In this example, friendFunction is declared a friend of the MyClass class and can access its private member, privateData....
For example, the tree-height function h(age) = age×20 makes no sense for an age less than zero. ... it could also be letters ("A"→"B"), or ID codes ("A6309"→"Pass") or stranger things. So we need something more powerful, and that is where sets come in:A...

An example of a virtual function with C++ Let’s see what a virtual function in C++ looks like in action. class Pet { public: virtual ~Pet() {} virtual void make_sound() const = 0; }; class Dog: public Pet { public: virtual void make_sound() const override { std::cout <<...
Recently I had this problem with a Python/Tkinter app where editing text in one text entry field changed the text in another as I typed :) Here is an example on how you might use function id() to trace where those references are. By all means this is not a solution covering all poss...
data_type = data type (also known as cast operator) to which the expression is to be converted. To understand typecasting, consider this example. float (num)+ 3.5; //num is of int type In this example, float () acts as a conversion function which converts int to float. However, thi...

(x),h(x),s(t), etc, to keep track of, and work with, more than one formula in any single context. With function notation, we can now use more than one function at a time without confusing ourselves or mixing up the formulas, leaving ourselves wondering "Okay, which 'y' isthisone...
