C++ > Pointers Code Examples

Program has 'three functions' which receives 2 pointers reference. Three functions returns int, float and double sum of numbers. So this c++ tutorial use the following concepts. Write
C++ Language program sample which passes a "Reference" to a Function and Function has a 'pointer' as argument. Keep the return type void & display result in main body. Apply any

To add two numbers using pointer in the C++, you have to enter the 2 number, then make 2 'pointer' type variable of same type say *ptr1 and *ptr2 to initialize the address of both the
Example of using this 'pointer' is to return the "Reference of current object" so that you can chain "function calls", this way you can call all the functions for the current object in one go.
The pointer is a C++ programming data type whose value refers directly to (or "points to") another value stored elsewhere in computer memory using its address. Pointer examples
