  1. In Topic: Alternating sum problem with vector addition

    Another way to solve it would be to use a single for loop that loops through the elements in the vector and then a if condition in the loop that tests whether the index is even or odd.

    Hint: To test even and odd use the modulus operator %



    I was using the modulus op % but my stupid self used an if/else instead of a loop...thanks again Zereo :)

  2. In Topic: Alternating sum problem with vector addition

    Posted 30 Apr 2013

    	//alternating sum 
	for (int i=0;i<v.size();i+=2)
		altsumEven+=v[i];
	for (int i=1;i<v.size();i+=2)
		altsumOdd+=v[i];

	altsum=altsumEven-altsumOdd;						// takes sum of all even positions and subtracts by sum of all odd positions in the vector



    Got it thanks alot :)

  3. In Topic: Finding min and max int in an array

    Ohh so that's why haha

    Yes did you not read my last comment. I knew the answer but it wasn't working and it was because I was forgetting a semicolon after [n-1] for the last element in the array...

    I apologize, turns out my comment didn't post for some reason but I figured it out a long time ago, was a stupid mistake.

    I can do that for the first element of the array, but how to do it for the last ?
