c++:

Assume that we initialize step prior to this section of code. Which value of step will cause it to print out "true"?

int result = 0;

for (int i=1; i<step; i++)

if (i%3 == 2)

result += i;

if (step == result)

cout << "true" << endl;

else

cout << "false" << endl;

choices:

4, 5, 6, or 7?

Please explain your answer

Answer #1 
Values of i and result in each iteration of the loop are
i = 1   result = 0
i = 2   result = 2
i = 3   result = 2
i = 4   result = 2
i = 5   result = 7
i = 6   result = 7

So, final value of result is 7.
So, step should be 7 to print "true"

7
