C++ Basic Algorithm: Exercise-41 with Solution
Write a C++ program to check if a given number is within 2 of a multiple of 10.
Sample Solution:
C++ Code :
#include <iostream>
using namespace std;
bool test(int n)
{
return n % 10 <= 2 || n % 10 >= 8;
}
int main()
{
cout << test(3) << endl;
cout << test(7) << endl;
cout << test(8) << endl;
cout << test(21) << endl;
