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
        for(int i=0;i<n;i++){
                    if(cb->count>0) {
                                int value = cb->buffer[cb->tail];
                                            printf("%d " ,value);
                                                        cb->tail = (cb->tail + 1)%cb->capacity;
                                                                    cb->count--;
                                                                            }
                                                                            else{
                                                                                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;
