The Stack

Explore the concept of the stack in C programming to understand how local variables are stored and managed automatically during function calls. Learn about its LIFO structure, limitations on size, and how efficient stack use affects memory and program performance.

So far, we have seen how to declare basic type variables such as int, double, etc, and complex types such as arrays and structures. The way we have been declaring such variables, so far, puts these variables on the stack.

What is the stack?

It’s a special region of your computer’s memory that stores temporary variables created by each function (including the main function). The stack is a LIFO data structure that’s managed and optimized by the CPU quite closely. ...
