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 cmd[10];
    int val;
    for(int i=0;i<n;i++){
        scanf("%s",cmd);
    
    if(strcmp(cmd,"push")==0){
        scanf("%d",&val);
        if(top>=MAX-1)printf("Stack Overflow\n");
        else stack[++top]=val;
    }
    else if(strcmp(cmd,"pop")==0){
        if(top==-1)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;
}
