Tính trung bình cộng các số chia hết cho 3 trong C++

Question

Vì vậy, Ở đây, Hãy xem xét n số chẵn đầu tiên bắt đầu từ số không (0). và Chúng ta phải Hoàn thành đoạn mã để tính tổng của tất cả các số này chia hết cho 3 và sẽ phải In ra tổng

Nội dung chính Show

Bây giờ chúng ta hãy xem trong Phần mã hóa
Làm thế nào để mã chia hết cho 3 trong C?
Cách tìm số bị chia trong C?
Có bao nhiêu số chia hết cho 3?
Có bao nhiêu số có n chữ số chia hết cho 3?

Ví dụ

Thích nếu chúng tôi đầu vào. n = 5

Vì vậy, các số trong biến n có thể là 0,2,4,6,8

Ở đây chỉ có 6 chia hết cho 3 Vậy Tổng sẽ là 6

Bây giờ chúng ta hãy xem trong Phần mã hóa

Sử dụng vòng lặp

import java.util.Scanner;
public class Exercise1_3 {

public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
int n=sc.nextInt();
 // For Taking Input from User
int sum=0; //Initialized Sum

 for (int i=0; i

input: 10
// (0, 2, 4, 6, 8, 10, 12, 14, 16, 18) only 6 divides by 3 thus
output: 6

`Sử dụng vòng lặp While`

import java.util.Scanner;

public class Exercise1_3 {

   public static void main(String[] args) {

      Scanner sc = new Scanner(System.in);
      int n = sc.nextInt();
      int sum = 0;

      int count=0;

      while(count

input: 5
// (0, 2, 4, 6, 8) only 6 divides by 3 thus
output: 6

 Có một toán tử gọi là “mô đun” cho bạn biết số dư sau khi thực hiện phép chia cho hai số. Dấu phần trăm (%) được sử dụng cho việc này
Ví dụ. 7%3 == 1 vì 7 chia hết cho 3 hai lần, dư 1
Một vi dụ khac. 12%5 == 2
Vậy để kiểm tra một số có chia hết cho 3 hay không ta cần xác định xem số đó chia cho 3 có dư 0 không

Thời gian phức tạp. O(r – l), khi chúng ta đi từ l đến r
Không gian phụ trợ. O(1), vì chúng tôi không sử dụng thêm dung lượng. 
Phương pháp hiệu quả. 
 
Ta phải kiểm tra xem số đó có chia hết cho 2 không
Ta phải kiểm tra xem tổng các chữ số có chia hết cho 3 có nghĩa là số đó chia hết cho 3
Vì vậy, về tổng thể, chúng ta phải kiểm tra xem một số có chia hết cho cả 2 và 3 hay không và vì cả 2 và 3 đều là số nguyên tố cùng nhau nên chúng ta chỉ cần kiểm tra xem một số có chia hết cho tích của chúng không i. e. 6. 
Dưới đây là cách triển khai của phương pháp trên.

Làm thế nào để mã chia hết cho 3 trong C?
var number = 21; .  //The number is divisible by three.
Cách tìm số bị chia trong C?
C hỗ trợ toán tử modulo % , tính toán phần dư khi chia hai toán hạng . Bạn có thể sử dụng điều này để kiểm tra xem một số có chia hết cho một số hay không. Ví dụ - if(8 % 2) , nếu biểu thức đã cho ước tính 0 , thì 8 chia hết cho 2. 
Có bao nhiêu số chia hết cho 3?
3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 60, 63, 66, 69 . Có 33 số có 2 chữ số chia hết cho 3. 
Có bao nhiêu số có n chữ số chia hết cho 3?
Câu trả lời cần thiết được đưa ra bởi công thức Cấp số cộng. trong đó a = 102, d = 3,. n = 300. Vậy có 300 số tự nhiên chia hết cho 3.
