in this problem I believe it is asking me that if I enter a number the program will tell me if the integer is a multiple of 3, please help me understand this and show code with written comment.

PLEASE USE C++, THANK YOU.

#include

using std::cout;

using std::cin;

int main() {

int number;

std::cout << "Give me an integer: ";

//1. input an integer and assign it to number.

// your code here

//2.1. calculate if the entered number is a multiple of 3.

//2.2. if the number is a multiple of 3, print " The number is a multiple of 3." Otherwise, print " The number can not be divided into three equal groups."

// your code here

}
