Print “Even” or “Odd” without using conditional statement

Write a C/C++ program that accepts a number from the user and prints “Even” if the entered number is even and prints “Odd” if the number is odd. You are not allowed to use any comparison (==, <, >, …etc) or conditional (if, else, switch, ternary operator,..etc) statement.

Method 1
Below is a tricky code can be used to print “Even” or “Odd” accordingly.



using namespace std;

int main()
  char arr[2][5] = {"Even", "Odd"};
  int no;
  cout << "Enter a number: ";
  cin >> no;
  cout << arr[no%2];
  return 0;


arr = ["Even", "Odd"]
print ("Enter the number")
no = input()
print (arr[int(no) % 2])

Method 2
Below is another tricky code can be used to print “Even” or “Odd” accordingly. Thanks to student for suggesting this method.

int main()
    int no;
    printf("Enter a no: ");
    scanf("%d", &no);
    (no & 1 && printf("odd"))|| printf("even");
    return 0;
