Given the following code, what is the value of `result`?

int a = 7;
int b = 3;
double result = (double)(a / b) * 2.0;

  1. 4.666...

  2. 4.0

  3. 4.666...

  4. 4.666...

  5. 4.666...

Show answer & explanation

Correct answer

4.0

Explanation

First `a/b` is integer division because both operands are ints: 7/3=27/3 = 2. Then that result is cast to `double` giving `2.0`, multiplied by `2.0` gives `4.0`. The cast applies only to the result of the division, not to the operands themselves.
