C Stack Input Output Rules Explained

In the C language, the input and output rules for stacks follow the principle of Last In First Out (LIFO). This means that the data element that was last added to the stack will be the first one to be removed, while the data element that was first added to the stack will be the last one to be removed.

When data elements are pushed into the stack, they are added to the top of the stack; when data elements are popped out of the stack, the data element at the top of the stack is taken out and removed. The data elements in the stack can only be accessed and operated on through the top of the stack.

In the C language, a stack data structure can be implemented using arrays or linked lists. The push function is used to add data elements to the stack, and the pop function is used to remove data elements from the stack. The input and output rules of the stack can help us implement common algorithms and data structures, such as reversing output and matching brackets.
