Question

Is it more efficient / better to do A or B?
A)
int i = 0;
for (i = 0; i < 100; i++)
for (i = 0; i > 200; i++) {}

B)
for (int i = 0; i < 100; i++) {}
for (int i = 0; i > 200; i++) {}

The thing I'm getting at is when dealing with multiple for loops, is it better to use the same integer or declare a new integer every time?

Answer 1

depends. If I isn't needed again then do A, if byou need i again somewhere in the loops etc do the B. I've done either.

Answer 2

Also in both for (int i = 0; i > 200; i++) {} byou wold do i = something.length or the highest # then do i--

Answer 3

so it would be for( int i = size; i > 0; i--)

Answer 4

no medal? :(
