Opcode Artisan: C++ Code Snippets

Dear students, last year while I'm studying C++, there are lots of snippets I've working on. And I'd like to share it with you only for educational purposes. You may download my C++ sample projects from the links below. Enjoy!

Odd and Even Numbers


void main(){
   int num = 0;
   cout << "Please input any number:";
   cin >> num;
   
   if(num/2 * 2!=num){
      cout<< endl <<endl;
      cout<< "You entered an Odd Number" <<endl <<endl;
   }else{
      cout<< endl <<endl;
      cout<< "You entered an Even Number" <<endl <<endl;
   }

   if(num<0){
      cout << "You entered a Negative Number" <<endl <<endl;
   }else{
      cout << "You entered a Positive Number" <<endl <<endl;
   }

   if(num%3==0){
      cout << "The number is divisible by 3" <<endl <<endl;
   }else if(num%4==0){
      cout << "The number is divisible by 4" <<endl <<endl;
   }else if(num%5==0){
      cout << "The number is divisible by 5" <<endl <<endl;
   }
}
