Problem:
Consider the following method.
public static helper(int m, int n)
{
int c = 0;
while (m > n)
{
m -= n;
c += 1;
}
}
Which of the following operations does the method helper
implement?
- calculating a power,
mn
- integer division,
m / n
- integer division,
m % n
- integer multiplication,
m * n
The correct answer is b. The variable c
counts how many times n
can be subtracted from m
, or (stated another way) how many times n
can evenly "go into" m
. This is integer division.
