Question

write an algorithm to compute the sum of odd and even upto N. ​

Answer 1

Explanation:

The algorithm as :

Step 1: Start.

Step 2 : Input N.

Step 3 : sume = 0.

Step 4 : sumo = 0.

Step 5 : ctr = 1.

Step 6 : while (ctr < = N). If (ctr mod 2 = 0) sume = sume + ctr else sumo = sumo + ctr.

Step 7: Print “sum of even number is” sume.

Step 8: Print “sum of odd number is” sumo.

Step 9: End

Answer 2

Answer:

The program output is also shown below.

•int i, num, odd_sum = 0, even_sum = 0;

•printf("Enter the value of num\n");

•scanf("%d", &num);

•for (i = 1; i <= num; i++)

•if (i % 2 == 0)

•even_sum = even_sum + i;

•odd_sum = odd_sum + i;

•printf("Sum of all odd numbers = %d\n", odd_sum)
