Which array number is biggest.

[justutiz]

Hi, how can i know which array number is biggest?

I need to know the number ant which.

Example: a[5] = {1, 2, 5, 4, 3}

Bigest number is third and this is number 5.

How do you think you would solve this problem? What have you tried?

I have a mind with a lot of 'if'. If number 1 is biggest than other, then first and so on. but i think you guys have a greatest idea.

but i think you guys have a greatest idea.

The "greatest idea" is to use max_element. There is no need for if() statements.

To get the position, use std::distance to get the "distance" between the return value of max_element, and &a[0].

The max_element will return a pointer to the largest element, so all you need to do is get the distance between that pointer and the beginning of the a[] array.

In other words, two lines of C++ which I won't write (it's all in the links describing these two functions).

Something tells me that this is a pre-STL exercise.
“for” loop, may be?
