Odd or Even

 This is a simple program to illustrate the coding flow.

 Since all even numbers are divisible by 2 

 Algorithm:

           READ input into number

           IF MOD( number , 2 ) IS EQUAL TO ZERO THEN number IS even

           IF MOD( number , 2 ) IS NOT EQUAL TO ZERO THEN number IS odd.

Code Listing:

1. int main()
2. {
3.     int n;
4.     
5.     printf ("Enter a number: ");
6.     scanf ("%d",&n);
7.  
8.     if (n%2 ==0 ) {
9.             printf ("The number is Even");
10.     } else {
11.             printf ("The number is Odd");
12.     }
13. 
    
14.    getch();
15.    return 0;
16.  
17. }
