Algorithm
Problem Name:
In this HackerRank Functions in C++ programming problem solution,
A for loop is a programming language statement which allows code to be repeatedly executed.
The syntax is
for ( <expression_1> ; <expression_2> ; <expression_3> )
<statement>
- expression_1 is used for intializing 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 is
for(int i = 0; i < 10; i++) {
...
}
In this challenge, you will use a for loop to increment a variable through a range.
Input Format
You will be given two positive integers, a and b (a <= b) separated by a newline.
Sample Input
8
11
Sample Output
eight
nine
even
odd
