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] = { 0 };
    char cmd[5] = { 0 };

    int value = 0;
    int top = -1; 

    for(int i =0; i < n; i++){
        scanf("%s", cmd);

            if(strcmp(cmd , "push") == 0) {
                scanf("%d", &value);

                if(top == (MAX - 1)){
                    printf("Stack Overflow\n");
                }
                else {
                    Stack[++top] = value;
                }
            } else if (strcmp(cmd , "pop") == 0) {
                if(top < 0) {
                    printf("Stack Underflow\n");
                }
                else {
                    printf("%d\n",Stack[top--]);
                }
            }
    }
}

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

    process_stack(n);
    return 0;
}
