Answer

Answer:

D. The program displays the sum of the odd integers from 1 to 19.

Explanation:

Step1: Initial values

count = 1, sum = 0

Step2: First iteration

sum = sum + count = 0+1 = 1, count = count + 2 = 1 + 2 = 3

Step3: Second iteration

sum = sum + count = 1+3 = 4, count = count + 2 = 3 + 2 = 5

Step4: General pattern

count starts at 1 and is incremented by 2 each time. It will take on values 1, 3, 5, 7, 9, 11, 13, 15, 17, 19 in 10 - iterations. And sum accumulates these odd - numbered values. So the program calculates the sum of odd integers from 1 to 19.
