Codiga Code Snippet: Round the number to nearest ten

int round(int n){
    int a = (n / 10) * 10;
    int b = a + 10;
    return (n - a > b - n)? b : a;
  }

Round the number to nearest ten

round() calculates the remainder of a number divided by 10, and then adds 10 to that number to create the new round number.
