How can I print integers of this sequence with a for-loop: (1, -2, 3, -4, 5, -6, 7, -8, 9, -10)?

Question

What's the best way to print these integers? I want every other integer to be positive and every other to be negative.

I've tried this and it works but I wonder is there a better way to do it.

#include <iostream>

using namespace std;

int main(){
    for(int i=1; i<=10; i++){
        if(i%2==0) i*=-1;
        cout<<i;
        if(i%2==0) i*=-1;
    }
}
