Call by value and call by reference in c: So there are two ways to pass

So there are two ways to pass parameters to functions. Please note that the C language only supports pass by value . We achieve pass by reference effect with the help of pointer feature of C . In C++ , we can either use pointers or references for pass-by- reference . Pass by Value In pass by value , the function receives a copy of the variable's value . In this tutorial we will learn to use pointers with functions in C programming language. Learn the difference between call by value and call by reference in C programming with examples. See how to pass parameters to functions using these methods and how they affect the original values. Learn how to create functions in C and how Call by Value or Call by reference works while calling functions in C .
