Call-By-Value and Call-By-Reference

There are two ways to pass data to the function in C/C++. Pass-By-Value and Pass-by-Reference are equally important features of C/CC++. The time complexity of programs using pass-by value and pass-By reference is almost similar. When to use Pass-BY-Value is when we want to calculate the value of a particular function without modifying the values of arguments passed. To avoid bugs caused due to memory stack issues, use pass-via-reference to update a variable's value.
