Hello there! My code isnt the most optimal, but i used my knowledge of switch case and solved this:

int main(){
	int a, b;
	cin >> a >> b ;
	for(int i=a; i<=b; i++){
		if(i <= 9 && i >= 1){
				switch(i){
				case 1:
					cout << "one" << endl;
					break;
				case 2:
					cout << "two" << endl;
					break;
				case 3:
					cout << "three" << endl;
					break;
				case 4:
					cout << "four" << endl;
					break;
				case 5:
					cout << "five" << endl;
					break;
				case 6:
					cout << "six" << endl;
					break;
				case 7:
					cout << "seven" << endl;
					break;
				case 8:
					cout << "eight" << endl;
					break;
				case 9:
					cout << "nine" << endl;
					break;
				default:
					break;
				}
		}else{
			if(i%2==0){
				cout << "even" << endl;
			}else{
				cout << "odd" << endl;
			}
		}
	}
	return 0;
}

include

using namespace std;

int main() {

int a, b;
cin >> a >> b;

string num[] = {"one", "two", "three", "four", "five", "six", "seven", "eight", "nine"};

for (int i = a; i <= b; i++){
    if(i >= 1 && i <= 9){
        cout << num[i - 1] << endl;
    }
    else {
        if (i % 2 == 0 && i > 9){
            cout << "even" << endl;
        }
        else {
            cout << "odd" << endl;                
        }
    }
}
return 0;

}

how do I obtain multiple inputs without sstream? am i suppose to do sstream? (more than a and b)

Great solution here! I think using a switch statement for the numbers 1 through 9 makes it more readable. However, using a simple array for the numbers, as shown in other solutions, can make the code more concise and easier to maintain. I recently faced a similar challenge with device troubleshooting, where knowing the specific behavior of each part helped me diagnose issues faster.
