Implement Stack Using Array with Push and Pop Operations

Code

#include <stdio.h>
#include <stdint.h>
#include <string.h>

#define MAX 10

void process_stack(int n) {
    // Your logic here
    int Arr_Stack[MAX];
    int top = -1;
    char str[10] ;
    int val;
   while(n)
   {  
        scanf("%s",str);
      if(strcmp(str,"push")==0)
        {
           scanf("%d",&val);
           if(top>=MAX-1)
           {
            printf("Stack Overflow\n");
           }else{
            Arr_Stack[++top]=val;
           }
        }else if(strcmp(str,"pop")==0)
        {
            if(top==-1)
            {
                printf("Stack Underflow\n");
            }else{
                printf("%d\n",Arr_Stack[top--]);
            }
        }
        n--;
   }

    
}

int main() {
    int n;
    scanf("%d", &n);
    getchar(); // Consume newline after number

    process_stack(n);
    return 0;
}
