How to read from text file low, high temperature pairs from the file until end-of-file, use to print asterisk in between low and high temperature.

Write a program to read the data from this file and display a temperature bar chart. The program should: 
1) Display a short message from the programmer with the programmer's name, describing what is about to display. For example, if your name is Whippersnapper and you are producing a bar chart, begin with the message: Whippersnapper's bar chart: 
2) Attempt to open the file lohiF.txt mentioned above. If the file is not found, handle the situation appropriately with a good error message, including the name of the file not found, then stop. Do not attempt to display a chart if no data is available. An even better error message might include a short description of the expected file format. 
3) If the file opens OK, read the first full line of the file. This line contains a brief description of the data in the file. Above the chart you are about to make, display the brief description you read from the file so the user knows what this chart represents. 
4) Use all the data in the file to display a bar chart showing temperature ranges for 12 months. 
5) Make the program more flexible: read low, high temperature pairs from the file until end-of-file (instead of exactly 12 times). It should work if there are more or less than 12 months of temperature data. Handle temperature values until end of file.

The program should contain test results at the bottom in a comment. This particular bar chart shifts the values to the right, assuming that 32 F, freezing, is at the far left. You can modify this behavior if you like, but you should at least show the range from low to high temps in the file. 
The program can assume: 1) The first line of the file has a string that describes the data: 2) Temperature values are within the range of -999 to +999 degrees. 3)At least 1 month of temperature values are provided. 4)No more than 24 months of temperature data. 5)The temperatures start with month 1, January. 6)Temperature values are provided in pairs: low-temp high-temp with whitespace between temps. 6) It is possible the file may not be not found.
The text in the file as:-
Austin Average Monthly low high Temperatures (Fahrenheit) Years 2010 - 2019
41 63
46 67
53 75
59 81
67 87
74 94
76 98
76 100
72 93
61 83
50 72
44 64

The output should look like this one.
