i'm using xcode since i have a mac and its saying build succeeded and asks me me to enter input file name, and i saved the numbers above on my desktop as "input" its an rtf file and when i enter input.rtf or input it says file does not exist

instructions:

You changed your mind about how to read the temperature measurements for your home weather station. Instead of reading them directly from a sensor every hour, you have decided to have the measurement instrument build a daily file with 25 entries. Each entry contains the temperature in degrees F at the top of each hour nothing else. The first reading corresponds to midnight, the second to 1 AM, and so on. Then, in addition to writing the input columns and the calculated output (max, min and average temperatures) to the screen (as done for HW #4), your program will also write the same output to a file a different one than the one containing the hourly temperatures.

So, take the program you wrote for HW #4 and modify it to do the above. A text file called input-temps.txt has been posted to the miscellaneous postings page in Webcourses that contains 25 temperature values to be read for each day. Your program should read those values and save them to an array. When finished calculating the max, min and avg, it should write those values, along with the hourly temperature table, to an output file that you will call output-temps.txt. Therefore, do the following:

1) Delete the get_values() function in your existing code. You will no longer need it.

2) In its place, define a read_temps() function that will ask the user the name of the file to be read, reads that file, and saves the read values to an array.

3) The calc_values() function you already have should be called from main(). Then main() needs to pass the hourly temperature array to calc_values() by reference. In addition to calculating the max, min and avg as it did for HW #4, it will write those values to the output-temps.txt external file. The contents of the output external file should be formatted in the same manner as in the output to screen.

You should submit the source code as usual. Do not submit the output-temps.txt external file as written by the program. The program should do that when it is executed during grading.

These are the numbers for input-temps.txt :

7

67

69

71 77 79 80 80 82 85 87 88 91 93 94 95 95 96 94 90 85 82 81 77 74
