Because

You are not taking input inside loop
You are not adding input value inside loop

Even numbers are those numbers which are multiple of 2 and returns reminder 0.

If you don't want to take input then do this:

int i = 1, sum;

do {
printf("the value of i is %d\n",i);

if(i % 2 == 0) {
printf("it is even number\n");
sum += i;
} else {
printf(" it is odd number\n");
}

i++;
} while(i <= 10);

printf(" sum of even no. is %d", sum);
