For the life of me I can not figure out how to efficiently code placing three integers in ascending order! I can do it with a bazillion lines of code but I'm certain there is a shorter way.
int num1;
int num2;
int num3;
int min;
int mid;
int max;
(I'm too embarrassed to write those bazillion lines of code!)
any help would be greatly appreciated.

what do you mean?
something like this will work
int num1,num2,num3;
or
int min,mid,max;

whoops! I meant to say that the 3 integers are read in from a file ... then need to be sorted into ascending order then displayed on the screen. I just don't know how to write the tests using say five lines of code.
Well this is the algorithm - all you need to do is arrange the input, and figure out how to swap two variables
Code:if ( a > b ) swap(a,b); if ( b > c ) swap(b,c); // c is now the largest if ( a > b ) swap(a,b); // a and b are also in order
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
