Question

Computer class 9 java

Answer 1

#include <iostream> using namespace std; int main() { int n; cout << "Enter an integer: "; cin >> n; if ( n % 2 == 0) cout << n << " is even."; else cout << n << " is odd."; return 0; }

Output

Enter an integer: 23 23 is odd.

In this program, if..else statement is used to check whether n%2 == 0 is true or not. If this expression is true, n is even if not n is odd.

You can also use ternary operators ?:instead of if..else statement. Ternary operator is short hand notation of if...else statement.
