My code is experiencing the segementation fault even I tried to bound my input parameters as I believed that inputs are the reason of array out of bound errors.

Can someone please help me relaize where I am going wrong

CODE :

#include <iostream>
#include <cstdio>
using namespace std;

int main() {
    string words[9] = {"one","two","three","four","five","six","seven","eight","nine"};
    int numbers[9] = {1,2,3,4,5,6,7,8,9};
    int input_a , input_b;
    cin >>input_a>>input_b;
  
    for( int i = input_a - 1 ; i <= 9;i++) {
        cout << words[i]<<endl;
    }
    if(input_a % 2 == 0){
        cout << "even"<< endl;
    }
    if (input_b % 2 == 0){
        cout << "even" << endl;
    }
    
    else{
        
        cout << "odd" << endl;
    }
    return 0;
}

Expected INPUT

8
11

Expected OUTPUT
eight
nine
even
