C++ drop lowest score

[plang007]

I can not seem to figure out how to drop the lowest score. When I run it it says the lowest score dropped was 0. How do I fix this?

Putting this in CODE tags would make this a lot easier to read...

[plang007]

how do you put it in code tags. I am new to this website.

Click Edit on your post, then highlight all of your code, and push the "CODE" button on the options above.

Here is the problem.

int low;  // You never set low equal to any value

cout << "Enter four interger scores with a space in between: " ;
cin >> score1 >> score2 >> score3 >> score4 ;

cout << "The test scores enetered are: " << score1 << " " << score2 << " " << score3 << " " << score4 << endl;
sum = score1 + score2 + score3 + score4;
low = score1; // set low equal to the first score
// now test the rest of them and change if needed.
if(low > score2)
  low = score2;
if(low > score3)
  low = score3;
if(low > score4)
  low = score4;

Do you get any run time errors ? I didn't go all over youre code but it seems that variable low hasn't been initialized.

[plang007]

I did not get any run time errors

[MasterGberry]

Read my post up above, you are not initializing the int variable low.

Thanks for all your help. I got it to work.
