   1. For Loop
   
   

Objective

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

Solution  C++ :

#include <iostream>

using namespace std;

int main() {

    int a, b;

    string represent[10] = {"zero", "one", "two", "three", "four",\

        "five", "six", "seven", "eight", "nine"};

    cin >> a >> b;

    for(int i = a; i <= b; i++) {

        

        if(i > 9) {

            if(i % 2 == 0)

                cout << "even\n";

            else cout << "odd\n";

        }

        else {

            cout << represent[i]<<endl;

        }

    }

    return 0;

}
