I know this is supposed to train your if/else conditons and the task has constraints by giving you input how it wants it to but solution like this could save you unnecessary lines of code:

#include <iostream>
#include <string>
#include <array>

int main() {
    std::string input;
    std::getline(std::cin, input);
    int n = std::stoi(input); // Assumes valid input per problem constraints

    constexpr std::array words = {"one", "two", "three", "four", "five", 
                                  "six", "seven", "eight", "nine"};

    if (n >= 1 && n <= 9) {
        std::cout << words[n - 1];
    } else if (n > 9) {
        std::cout << "Greater than 9";
    }

    return 0;
}

int main() { string n_temp; getline(cin, n_temp);

int n = stoi(ltrim(rtrim(n_temp)));

// Write your code here
if(n == 1){
    cout<<"one";
}
else if (n==2){
    cout<<"two";
}
else if (n==3){
    cout<<"three";
}
else if (n==4){
    cout<<"four";
}
else if (n==5){
    cout<<"five";
}
else if (n==6){
    cout<<"six";
}
else if (n==7){
    cout<<"seven";
}
else if (n==8){
    cout<<"eight";
}
else if (n==9){
    cout<<"nine";
}
else{
    cout<<"Greater than 9";
}

return 0;

}

int n; cin >> n;

if (n >= 1 && n <= 9) {
    switch(n) {
        case 1: cout << "one"; break;
        case 2: cout << "two"; break;
        case 3: cout << "three"; break;
        case 4: cout << "four"; break;
        case 5: cout << "five"; break;
        case 6: cout << "six"; break;
        case 7: cout << "seven"; break;
        case 8: cout << "eight"; break;
