In the code segment below, assume that the int variable n has been properly declared and initialized. The code segment is intended to print a value that is 1 more than twice the value of n. Missing code */ system. out. print(result); which of the following can be used to replace*/ missing code */ so that the code segment works as intended?
a. int result = 2 * n; result = result + 1.
b. int result = n + 1; result = result * 2.
c. int result = (n + 1) * 2.

Answer:

Option a is the correct answer for the above question.

Explanation:

The question wants the output of "one more than the double of n".It is also called as "2n+1".Then the value of n will be multiplied by 2 and then 1 will be added on it.

It is formed by the option 'a' which have two statements. The first statement multiplies the value of n by 2 and stores it into result and the value becomes twice of n and then the second statement adds the 1 value to the result value and again store the value in the result. So the result variable stores the (2*n) +1 value. Hence Option a is correct while the other is not because--

  • Option b gives the result value as "2(n+1)", which can be 2*n+2.
  • Option c gives the result value as same as the option b.
