Given the formula for converting Fahrenheit (F) to Celcius (C): C = 5/9 x (F - 32), where C is the unit of temperature in Celcius and F is the unit of temperature in Fahrenheit. Write a complete C++ program that reads in a list of data F from a text file, then calculates the values of C using the formula given. The program should use an array to store the values of F as example shown in Figure 4. 13.29 29.76 14.81 23.78 29.37 .. Figure 4: Example of data F in the input file The program then prints a summary output onto the screen and the detail output into a text file as shown in Figures 5 and 6. Grades ‘H’ mean high temperature; ‘M’ is medium temperature and ‘L’ is low temperature. Your program must define several functions at least as listed in Table 3. You are also required to apply the concept of parameter passing to these functions. Average of the temperature: 32.3 Number of high temperature: 2 Number of medium temperature: 20 Number of low temperature: 8 Figure 5: Example of output on the screen C(Celcius) F (Farenheit) Description ========== ========= ===== 54.94 130.89 H 19.86 67.75 L 93.70 200.67 H 13.77 56.78 L : : : : : : Figure 6: Example of content in the output file Function Description readFile This function reads in a list of numbers from a text file and stores them into a onedimensional array.
