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 = (*cb).tail;

    for(int i = 0; i < n; i++) {
        if( i < (*cb).count) {
            printf("%d ", (*cb).buffer[temp]);
            temp = (temp + 1) % 10;
        } else {
            printf("NULL ");
        }
    }
    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;
}
