For Loop.cpp-HackerRank

Problem-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".

Solution-

#include <iostream>

#include <cstdio>

using namespace std;

int main()

{

int a,b;

cin >> a>> b;

string s[9] = {"one","two","three","four","five","six","seven","eight","nine"};

for(int i=a; i<=b;i++)

{

if(i <= 9)

{

cout << s[i-1] << endl;

}

else

{

if(i%2 ==0)

{

cout << "even" << endl;

}

else

{

cout << "odd" << endl;

}

}

}

}
