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 temp_tail = cb->tail;
    int temp_count = cb->count;
    while((temp_count > 0) &&(n>0)){
        printf("%d", cb->buffer[temp_tail]);
        printf(" ");
        temp_tail = (temp_tail + 1)%cb->capacity;
        temp_count--;
        n--;
    }
    while(n > 0){
        printf("NULL");
        n--;
        if(n > 0){
            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;
}
