![]() These functions and local variables are stored in stack memory which we can see below image. In the below program, we can see that there are two main functions. We will understand the stack memory concept using the below example. How Stack Memory Works with an Example of a Program in C Language ![]() If there is no space for creating new objects, it throws a stack overflow error. This means that the value stored in stack memory is only available while the execution is still running, and it will be automatically erased once the task is completed. Memory allocated to stack lives until the function returns. It stores the variables, references to objects, and partial results. Stack is a linear data structure that is generally used when we need to follow the Last in First out (LIFO) manner. This allocated memory is released once the program execution is completed. A fixed amount of memory is allocated at compile time with the static allocation (Stack Memory). In dynamic allocation (Heap Memory), memory is allocated at the program run time. ![]() Memory allocation can be dynamic or static. What is Memory Allocation?Ĭomputer programs require a certain amount of memory to be allocated for execution. In this article, we will learn what is memory allocation, what is stack and heap memory, and how stack memory works with an example of a program in c language, when stack overflow (error) happens in stack memory, advantage and disadvantage of stack memory, how heap memory works with an example of a program in c language, advantage and disadvantage of heap memory and the difference between stack and heap.
