There are two ways that a function argument, or parameter, can be passed to it: by value or by reference. In the first instance, a copy of the variable is made when the function receives it. Hence, any changes made to the passed variable within the function end when the function return...
We can pass arguments into the functions according to requirement. C++ supports three types of argument passing: Pass by Value Pass by Reference Pass by Address Pass by Value In case of pass by value, we pass argument to the function at calling position. That does not reflect changes into ...
