Manipulate Series

1. Write a C program to print a Series of Integer Numbers,which is divisible by 3 from a given set of limits.

Sample Input: 

Start_value: 1
End_value: 10

Sample Output:

3, 6, 9

2. Write a C program to print a Series of Odd Numbers and Even Numbers. After Print Make an Average of all Printed Odd Numbers and Even Numbers.

Sample Output:

The Even Numbers are: 2, 4, 6, 8, 10
The Odd Numbers are: 1, 3, 5, 7, 9

The Average of Even Numbers: 6

{
int start, end, i ;

printf("Start_Value: ");
scanf("%d", &start);
printf("End_Value: ");
scanf("%d", &end);
printf("\n\n");
for(i=start ; i <= end ; i++)
{
if(i%3 = = 0)
printf("%d, ", i );
}

getch();
return 0;
}

aveodd=(float)(sumodd)/odd;
printf("\n\nThe Average of Even Numbers: %.2f", aveeven);
printf("\n\nThe Average of Odd Numbers: %.2f", aveodd);

getch();
return 0;
