« C Language »

My Dear candidates, C language does not support the concept of “Call by Reference”. Why here I’m raising this issue is just because, frequently in a lot of interviews there is a question “What is the difference between Call by Value and Call by Reference?”.

Actually C doesn’t have a special flavor of variable aka “Reference Variable”. So how can it support or allow “Call by Reference”.

[Reference variables are introduced in C++.]
