Variables are the most important part of any programming language. Any programming language is incomplete without a variable. We can also say that without variables, the program cannot run. Like any other programming language, the C++ language also needs variables to run their program. Variables ar...

The asterisk is in fact used on a third occasion, when multiplying two values. int i = 999; int *p = &i; int j = *p; // 999 A reference is a simplified version of a pointer; it can be regarded as a constant form of a pointer. A reference variable must be initialized to refer...

. When we pass a pointer as an argument instead of a variable then the address of the variable is passed instead of the value. So any change made by the function using the pointer is permanently made at the address of passed variable. This technique is known as call by reference in C....
