If anyone can help me finish this and point out what had to be done to make the program work, that would be great.
-ask for how many days user wants to enter from 1-365 (validate)
-ask for temperature for each days between -60 and 90 degrees celsius (loop, validate)
-convert each value to fahrenheit (funtion)
-output results (function)
Problem
-the users should input a int celsius number, a whole number but it converts to a double fahrenheit number
- for this code
cout << "Celsius temperature for Day " << i+1 << " : ";
*(days + 1) = GetValidInt("", TEMP_MIN, TEMP_MAX);
it outputs and waits for the input on a new line...how can i make it wait for input on the same line?
