    Sol using switch:

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

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

    switch (n) {
        case 1:
            printf("one");
            break;
        case 2:
            printf("two");
            break;
        case 3:
            printf("three");
            break;
        case 4:
            printf("four");
            break;
        case 5:
            printf("five");
            break;
        case 6:
            printf("six");
            break;
        case 7:
            printf("seven");
            break;
        case 8:
            printf("eight");
            break;
        case 9:
            printf("nine");
            break;
        default:
            printf("Greater than 9");
    
    }

    return 0;
}

    Exercise was ment to teach conditional statements, so I used them all without anything else which would be (cheating in my opinion).

    I changed input type int n to unsigned int n because of given constraints. It says that there can't be negative numbers, so we should use a proper type.

    I have put Greater than 9 condition before all other because it is more likely that user will input greater number than 9. This way we prevent 9 statement checks which will make code execute faster in most cases.

    This is the code:

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

		if (n > 9)
        cout << "Greater than 9";
    else 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
        cout << "nine";

    include

    using namespace std; int main(){ int n; cin>>n;

    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;

    vector <string> words = {
        "",
        "one",
        "two",
        "three",
        "four",
        "five",
        "six",
        "seven",
        "eight",
        "nine"
    };
    if (n>=1 && n<=9) {
        cout << words[n];
    } else {
        cout << "Greater than 9";
    }

    The right approach:-

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

return 0;

    }
