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 v[MAX], index = 0;
    char s[5];
    int x;
    while(n--){
        scanf("%s", s);
        scanf("%d", &x);
        if(strcmp(s,"push") == 0){
            if(index<MAX){
                v[index] = x;
                index++;
                } else printf("Stack Overflow\n");
        } else if(strcmp(s,"pop") == 0){
            if(index > 0){
                printf("%i\n", v[index - 1]);
                index--;
            } else printf("Stack Underflow\n");
        }

    }
}

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

    process_stack(n);
    return 0;
}
