You really should explain more than just "it won't work" if you want good help.
What exactly won't work?
Does it not run correctly or does it not compile? It is an important difference. If it is a compile-time error, posting the errors your compiler spits out is also helpful.

For your problem, the first error I see is on line 3 of your showMenu function, you have double quotation marks around "hot", but you need to escape these inner quotes by using \" instead of just "
http://en.cppreference.com/w/cpp/language/escape

Also, variable names cannot contain spaces. You can use underscores instead.

float highest_temperature;
float lowest_temperature;
highest_range=0;

And please use code tags for readability
