Question

I have an assignment that is the following:

For a given integer array, find the sum of its elements and print out the final
result, but to get the sum, you need to execute the function for_each() in STL
only once (without a loop).

As of now this is my code:

void myFunction (int i) {
cout << " " << i << " " <<  endl;
} 


int main() {

int array[] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };

vector<int> v(array[0], array[10]);

for_each( v.begin(), v.end(), myFunction);

return 0;
}

But for some reason the output shows up as 4198853, at first I thought it was a memory address but I figured out that was wrong. Any idea’s as to what I might be doing wrong?

Answer 1

why not just:

for_each( array, array+10, myFunction);

I’m quite sure that int* can be used as iterator

EDIT: just checked this, it can indeed
