For loop C++

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

The syntax for this is

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

• expression_1 is used for intializing variables which are generally used for controlling 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 will be

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

Input Format

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

Output Format

For each integer  in the 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

#include <iostream>

#include <cstdio>

using namespace std;

int main() {

int i,c,b;

string a[11]={"even","odd","one","two","three","four","five","six","seven","eight","nine"};

cin>>c>>b;

for(i=c;i<=b;i++)

{

if((i>9) && (i%2==0))  cout<<a[0]<<endl;

else if((i>9) && (i%2!=0)) cout<<a[1]<<endl;

else    cout<<a[i+1]<<endl;

}

return 0;
