Peek N Bytes from Circular Buffer

Code

#include <stdio.h>

typedef struct {
    int buffer[10];
    int head;
    int tail;
    int count;
    int capacity;
} CircularBuffer;

// Write your logic inside this function
void peek_bytes(CircularBuffer *cb, int n) {
    // Your code here
    int cnt =cb->count;
    int t = cb->tail;
    for(int i = 0; i < n;i++)
    {
        if(cnt > 0)
        {
            printf("%d",cb->buffer[t]);
            t=(t+1)%cb->capacity;
            cnt--;
        }
        else{printf("NULL");}
        if(i < n-1)
        {
            printf(" ");
        }
    }
}

int main() {
    CircularBuffer cb = {
        .buffer = {10, 20, 30, 40, 50, 60, 70, 80, 90, 100},
        .head = 3,
        .tail = 7,
        .count = 6,
        .capacity = 10
    };

    int n;
    scanf("%d", &n);

    peek_bytes(&cb, n);

    return 0;
}
