For loop in c programming hackerrank solution

Problem

Objective

In this challenge, you will learn the usage of the for loop, which is a programming language statement that allows code to be repeatedly executed.
The syntax for this is

for ( <expression_1> ; <expression_2> ; <expression_3> )
    <statement>
  • expression_1 is used for initializing 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 will be

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

Task

For each integer n in the interval [a,b] (given as input) :

  •  If 1<= n , 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”.

Input Format

The first line contains an integer, a.The second line contains an integer, b.

Constraints :-

1<=a<=b<=10^6

Output Format

Print the appropriate English representation,even, or odd, based on the conditions described in the ‘task’ section.


Sample Input

8
11

Sample Output

eight
nine
even
odd

Another Solution

#include <stdio.h>
#include <string.h>
#include <math.h>
#include <stdlib.h>



int main() 
{
    int a, b;
    int n=0;
    scanf("%d\n%d", &a, &b);
  	for(n=a;n<=b;n++)
    {
    if(n==1)
    {
        printf("one\n");
    }
    if(n==2)
    {
        printf("two\n");
    }
    if(n==3)
    {
        printf("three\n");
    }
    if(n==4)
    {
        printf("four\n");
    }
    if(n==5)
    {
        printf("five\n");
    }
    if(n==6)
    {
        printf("six\n");
    }
    if(n==7)
    {
        printf("seven\n");
    }
    if(n==8)
    {
        printf("eight\n");
    }
    if(n==9)
    {
        printf("nine\n");
    }
     if(n>9)
    {
       if(n%2==0)
       {
           printf("even\n");
       }
       else {
       printf("odd\n");
       }    
    }

      }
    return 0;
