Problems

A for loop is a programming language statement which allows code to be repeatedly executed.

The syntax is

for ( <expression_1> ; <expression_2> ; <expression_3> )
    <statement>

• expression_1 is used for intializing variables which are generally used for controlling the terminating flag for the loop.
• expression_2 is used to check for the terminating condition. If this evaluates to false, then the loop is terminated.
• expression_3 is generally used to update the flags/variables.

A sample loop is

for(int i = 0; i < 10; i++) {
    ...
}

In this challenge, you will use a for loop to increment a variable through a range.

Input Format

You will be given two positive integers,  and  (), separated by a newline.

Output Format

For each integer  in the inclusive interval :

• If , then print the English representation of it in lowercase. That is "one" for , "two" for , and so on.
• Else if  and it is an even number, then print "even".
• Else if  and it is an odd number, then print "odd".

Note: 

 Sample Input

8
11

 Sample Output

eight
nine
even
odd

Code

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

int main() {
    // Complete the code.
    int a,b,i;
    char *str[] = {"one","two","three","four","five","six","seven","eight",
    "nine","even","odd"};
    cin>>a;
    cin>>b;
    for(i=a;i<=b;i++)
    {
        if(i<=9)
        {
            cout<<str[i-1]<<"\n";
        }
        else
        {
            cout<<str[9+(i%2)]<<"\n";
        }
    }
    return 0;
}
