   int main()
    {
       int n; //Declaration of variable
       cout<<"Enter a number:-";
       cin>>n;
       if(n%2==0) 
         cout<<n<<" is even no.";
       else
         cout<<n<<" is odd no.";
       getch();
    }

Check given number is even or odd using Conditional operator

  using namespace std;
   int main()
    {
       int n; //Declaration of variable
       cout<<"Enter a number:-";
       cin>>n;
       n%2==0?cout<<n<<" is even no.":cout<<n<<" is odd no.";
       getch();
    }

Check given number is even or odd using Switch case statement

#include<iostream>

       cin>>n;
       switch(n%2)
          {
           case 0:cout<<n<<" is even no.";
             break;
           case 1:cout<<n<<" is odd no.";
