c++ insertion in astack

To insert an element into a stack in C++, follow these steps:

1. Create a stack: Start by declaring and initializing a stack variable of the desired data type. For example, to create a stack of integers, you can use the std::stack<int> data structure.

2. Push the element: To insert an element into the stack, use the push() function. Pass the value you want to insert as an argument to the function. For example, if you want to insert the value 10 into the stack, you can write stack.push(10).

3. Explanation: The push() function adds the given element to the top of the stack. It increases the stack size by 1 and updates the top pointer accordingly. The newly inserted element becomes the top of the stack, and the previous top element is pushed down.

4. Repeat if needed: You can repeat the above steps to insert more elements into the stack. Each time you call the push() function, the new element will be added to the top of the stack.

Note: Make sure to include the necessary header file for using the stack data structure in C++. You can include the <stack> header file at the beginning of your code.
