Question

Write programs with loops that compute

a. The sum of all even numbers between 2 and 100 (inclusive).

b. The sum of all squares between 1 and 100 (inclusive).

c. All powers of 2 from 20 up to 220.

d. The sum of all odd numbers between a and b (inclusive), where a and b are

user inputs.

e. The sum of all odd digits of an input. (For example, if the input is 32677, the

sum would be 3 + 7 + 7 = 17.)

Answer 1

the logic for a and b would be:

//even numbers 2-100

var sum = 0;

var i;

for (i = 1; i <= 100; i++) {

  if (i%2 ==0){

sum = sum+ i;

}

}

//squares

var sumsquare = 0

var i=1;

while (i*i<=100) {

sumsquare= sumsquare +(i*i)

i++

}
