For Loop|||| hackerrank || C++ language || programming_info

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

Now here's the solution in C++:-

code snippet:
#include <iostream>
#include <cstdio>
using namespace std;
int main()
 {
      int a,b,n,i;
        cin >>a>>b;
        for(i=a;i<=b;i++)
            {
                n=i;
                if(1<=n && n<=9)
                    {
                    if(n==1)
                        {
                            cout <<"one"<<endl;
                        } 
                    else if(n==2)
                        {
                            cout <<"two"<<endl;
                        }
                    else if(n==3)
                        {
                            cout <<"three"<<endl;
                        }
                    else if(n==4)
                        {
                            cout <<"four"<<endl;
                        }
                    else if(n==5)
                        {
                            cout <<"five"<<endl;
                        }
                    else if(n==6)
                        {
                            cout <<"six"<<endl;
                        }
                    else if(n==7)
                        {
                            cout <<"seven"<<endl;
                        }
                    else if(n==8)
                        {
                            cout <<"eight"<<endl;
                        } 
                    else 
                        {
                            cout <<"nine"<<endl;
                        }
                    }
                    else if(n>9)
                        {
                            if(n%2==0)
                                {
                            cout << "even" <<endl;
                                }
                            else 
                                {
                            cout << "odd" <<endl;
                                }
                        }
            }         
    // Complete the code.
    return 0;
}
