Objective:
The objective of this assignment is to provide hands on experience of
Basic concepts of C/C++ language and Programming
Dealing with Data types
Conditional statements of C/C++ language
Repetition Structures (Loop)
Switch statement

Guidelines:
Code should be properly indented and well commented.
Follow C/C++ rules while writing variable names, function names etc
Use only dev-C++ for this assignment.

Assignment
Problem Statement:
You are required to write a C++ program using loop and switch statement. The program should display even or odd numbers from 1 to 50 depending upon the option given

Detailed Description:
The program should prompt the user for one character option (either ‘e’, ‘E’ or ‘o’, ‘O’).
It should respond in the following ways:

If user enters character option ‘e’ or ‘E’ then it should display the even numbers from 1 to 50.
If user enters character option ‘o’ or ‘O’ then it should display the odd numbers from 1 to 50.
Sample output of the program:

If user enters ‘e’ then it displays the even numbers from 1 to 50.
If user enters ‘E’ then it displays the even numbers from 1 to 50
If user enters ‘o’ then it displays the odd numbers from 1 to 50.
If user enters ‘O’ then it displays the odd numbers from 1 to 50.

there are two ways to stop the output
1. last statement in the main program should be
system("pasue");
2. last statement should be:
getch();
for the 2nd step you need to add one header file conio.h
in the beginning write #include<conio.h>
