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 stack[MAX];
    int top=-1;
    char command[20];
    int x;
    for(int i=0;i<n;i++)
    {
        scanf("%s",command);
        if(strcmp(command,"push")==0)
        {
            scanf("%d",&x);
            if(top==MAX-1)
           { 
            printf("Stack Overflow\n");
            continue;
            }
            else
            {
                stack[++top]=x;
            }
        }
        else if(strcmp(command,"pop")==0)
        {
            if(top==-1)
            {
                printf("Stack Underflow\n");
                continue;
            }
            else
            {
            printf("%d\n",stack[top--]);
            }
        }
    }
}

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

    process_stack(n);
    return 0;
}
