Temperature Conversion Program Errors

llind212 (21)
I have an assignment to write a program dealing with temperature conversion.I have to prompt the user for the scale and degree to be used and display both F and C equivalents of the temperature provided, rounded to two decimal places. If inappropriate input is provided for both scale and temperature, an error message needs to be displayed. I also need to include a temperature scale stating that appropriate temperatures are any values greater than or equal to absolute zero, -459.67F or -273.15C. I don't understand where I need to place this scale within my program. I also have an error coming up regarding my setprecision in the void getReusults function (line 84). My output is also incredibly off. If anyone could take a look at my program and provide me with any feedback/guidance, it would be GREATLY appreciated!

For the setprecision, you need to include #<iomanip>. Also, you have stray curly brace at line 18. You need curly braces after line 29 to go with the curly brace at line line 32.

Okay, great! Thank you so much.

I am getting errors on lines 11 and 34 and am unsure as to what they mean...
11: error: too many arguments to function `void getResults()'
34: error: at this point in file

Wrong function prototype: change line 10 to:
void getResults (float, float);

Convert char 'scale' (in main) to uppercase, before if statment, or you will get errors when entering small 'f' / 'c'
