This program was supposed to work. I got the example from a C++ book, all I did is changing the wording in the char array the program keep aborting with errors I simply cannot fix. And all those warnings what do they mean? Anyway here is the program and the errors.
=============================================
/* This program uses the selection sort algorithm to sort an
array in ascending order.
this will sort the names and their corresponding values

One problem is your declaration of the "coor" array.
Should be:
Try fixing that and see how it goes.

For example, the first element was FC but ony C get
displayed and the same forthe other twos. Any suggestions?
the same
char corres[3] = {'HP', 'FC', 'YN'}; // corresponding array
//error C2078: too many initializers - Why?
// in char corres......above code


The unsorted values are
1.5 - P
1.79 - C
2.29 - N

The sorted values are
1 - ¨d
1 - ¨d
2.29 - N

Press any key to continue
=====
if I use quotes "" in the corres array for the elements
I get 3 errors and warnings:
