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 end;
    if(n< cb->count)    end = cb->tail + n;
    else                end = cb->tail + cb->count;
    for(int x = cb->tail;x<end;x++)
    {
        printf("%d ", cb->buffer[x%10]);
    }    
    if(n> cb->count)
    {
        for(int x=0;x< (n-cb->count); x++)
            printf("NULL ");
    }
}

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;
}
