What have you tried so far?

You can use a for loop that starts a counter from 1 and increments it by 2 each time. For each alternate path through the loop multiply the counter by -1. You can check for the alternate path by toggling a bool variable to true and false.

I can only point you in the right direction.

#include
using namespace std;

int main()
{
int n=43, sum = 0,neg= 1;

  for(int i = 1; i <= n; i+=2) 
  {
	 
	sum += (i\*neg); 
	cout <<"i="<

#include main() { int n; cout<<"Enter the Number:"; cin>>n; for(int i=1,j=1;j<=n;i+=2,j++) { if(i==1) cout<

I see your C++ compiler is a bit dated.
