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 i = cb->tail;
    while(n)
    {
        if(cb->count<=0)
        {
            printf("NULL ");
        }
        else{
            printf("%d ", (cb->buffer[i]));
        }

        i = (i%cb->capacity)+1;
        if(i == 10){
            i = 0;
        }

        --cb->count;
        --n;
    }
    printf("\n");
}

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;
}
