Each stack node contains a value (element) and a pointer to the next node (next_pointer).<\/p>\n\n\n\n<p>Key operations includes push_operation, which adds a new node to the top of the stack, and pop_operation which removes and returns the top element while freeing its memory. <\/p>\n\n\n\n<p>The peek_operation function retrieves the top element without removing it, and isEmpty_operation checks if the stack is empty. The display_elements function traverses the stack to print all elements from top to bottom.<\/p>\n\n\n\n<p>The program handles stack underflow for empty stacks during pop and peek operations and ensures error handling for memory allocation failures. The main function demonstrates these operations by pushing elements onto the stack, displaying them, peeking at the top, popping an element, and verifying if the stack is empty. This implementation properly handles dynamic stacks, offering flexibility over fixed-size array-based stacks.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>#include &lt;stdio.h&gt;\n#include &lt;stdlib.h&gt;\n\n\/\/ Define the structure of a stack node\ntypedef struct Node {\n    int element;\n    struct Node* next_pointer;\n} Linked_Node;\n\n\/\/ Function to create a new node\nLinked_Node* creatingNode(int element) {\n    Linked_Node* newNode1 = (Linked_Node*)malloc(sizeof(Linked_Node));\n    if (!newNode1) {\n        printf(\"Memory allocation failed\\n\");\n        exit(1);\n    }\n    newNode1-&gt;element = element;\n    newNode1-&gt;next_pointer = NULL;\n    return newNode1;\n}\n\n\/\/ Push operation: Add an element to the top of the stack\nvoid push_operation(Linked_Node** top_pointer, int element) {\n    Linked_Node* newNode1 = creatingNode(element);\n    newNode1-&gt;next_pointer = *top_pointer;\n    *top_pointer = newNode1;\n    printf(\"Element = %d inserted onto the stack\\n\", element);\n}\n\n\/\/ Pop operation: Remove and return the top element of the stack\nint pop_operation(Linked_Node** top_pointer) {\n    if (*top_pointer == NULL) {\n        printf(\"Stack underflow!
