Example c program using stack

Stack Int32 : This constructor is used to create an instance of the Stack class which is empty and having specified initial capacity or the default initial capacity, whichever is greater. Collections namespace in your program with the help of using keyword. As shown in the below example. Push In Stack, you are allowed to remove elements from the stack.

Peek ;. Container objects hold data of a similar data type. You can create a stack from various sequence containers. If no container is provided, the deque containe will be used by default. We then use this syntax to define the std::stack:.

Step 1 We initially have an empty stack. The top of an empty stack is set to Step 2 Next, we have pushed the element 5 into the stack. The top of the stack will points to the element 5. Step 3 Next, we have pushed the element 50 into the stack.

The top of the stack shifts and points to the element Step 4 We have then performed a pop operation, removing the top element from the stack. The element 50 is popped from the stack. The top of the stack now points to the element 5. The stack::push functions adds new item to the top of stack. The stack size is increased by a 1 after the insertion.

The function takes this syntax:. The stack:: pop function removes the top element of the stack. This is the newest item of the stack. The stack size is reduced by 1 after the removal. Here is the function syntax:.
