Two Basic Operations on Stack
- PUSH
- POP
Push and Pop operation in stack in C : Algorithm
- PUSH(Stack, N, Item)
This algorithm will insert Item at top to Stack having size N. Here initial index for stack is 0.

Copy to Clipboard
- POP(Stack, N)
This algorithm will delete the top element from the Stack having size N. Here initial index for stack is 0.

Copy to Clipboard
C program to implement push and pop operations on a stack using an array is as follows:
Copy to Clipboard
Output :
Copy to Clipboard
[…] PUSH […]
