Algorithm for Stack using array






Algorithm:



Step1: Start

Step2: Read the case in ch and array size to n

Step3: Switch ch

        Case1,
           if top>=n-1, then print stack is overflow
           else,
            Read the element to item
            Set tpo=top+1
            a[top]=item

        Case2,
           if top<0, then print stack is underflow
           else
            Set a[top]=null
            top=top-1

        Case3,exit

Step4: print the Stack

Step5: stop
