Need help with understanding/calculating Output in an Array

[Tate]

The answer is "9" for this problem, but I can't figure out how to reach this conclusion. Could someone please explain to me (step-by-step) how I can calculate the correct output?

Here's the problem:

int arr[5] = {2, 6, 5, 7, 9};
int la = arr[0];
for (int c = 1; c < 5; c = c + 1)
{
    if (arr[c] > la)
    {
        la = arr[c];
    }
}
cout << la << endl;

THANKS!

if 9 is the answer, what is the question ?

I expect the explanations provided for an earlier question should guide you as to the sort of thought-processes which are required.

Basically, take a sheet of paper.
Write down on a separate line the names of the variables:

la

c

arr[c]

Next to the variable name, write down its current value.
Then work your way line-by-line through the for loop. Make a note of the new value of each variable as you step through the code.
