## C Programming Language 038

The following code shows how to write a program to find the sum of even numbers and the sum of odd numbers below 1000.

### Program

```
#include <stdio.h>
void main()
{
int i, n = 1000;
long int esum = 0, osum = 0;
for (i = 0; i < n; i++)
{
if (i % 2 == 0)
{
esum = esum + i;
}
else
{
osum = osum + i;
}
}
printf("Sum of odd numbers = %ld\n", osum);
printf("Sum of even numbers = %ld\n", esum);
printf("\n");
}
```

### Result

```
Sum of odd numbers = 250000
Sum of even numbers = 249500
```
