# For Loop in C++ – Hacker Rank Solution

### Objectives

A for loop is a programming language statement which allows code to be repeatedly executed.
The syntax for this isSyntax :

```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

Example :

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

#### Input Format

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

#### Output Format

For each integer n, in the interval [a,b]:

• If 1<=n<=9 then print the English representation of it in lowercase. That is “one” for 1, “two” for 2, and so on.
• Else if n>9 and it is an even number, then print “even”.
• Else if n>9 and it is an odd number, then print “odd”.

```8
11
```

```eight
nine
even
odd```

```#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;
}```
