Print the sum of odd number and even number separately of n number

To find sum of even and odd enter a number from keyboard. Use for loop to iterate from 1 to n. Use if -else to check the divisibility of 2. If diviseble by two then add number into even else add number into odd. Finally display sum of odd and even.

/* Print the sum of odd number and even number separately of n number */

#include<stdio.h>
#include<conio.h>
void main()
{
	int a,i,even=0,odd=0;
	clrscr();
	printf("Enter a number\t");
	scanf("%d",&a);
	for(i=1;i<=a;i++)
	{
		if(i%2==0)
			even=even+i;
		else
			odd=odd+i;
	}
	printf("\nsum of the even\t=%d",even);
	printf("\nsum of the odd\t=%d",odd);
	getch();
}
Output :

Enter a number 12

sum of the even =42

sum of the odd =36
