Thus far in this book, we have seen examples of programs that have taken input data from users at the keyboard. Most of these programs can receive their input from text files as well. A text file is a software object that stores data on a permanent medium such as a disk, CD, or flash memory. When compared to keyboard input from a human user, the main advantages of taking input data from a file are the following:

The data set can be much larger.

 The data can be input much more quickly and with less chance of error.

 The data can be used repeatedly with the same program or with different programs.

The writer did not follow my choice of topic (Food/Water Insecurity, Hunger, & Poverty), the paper was instead written about Climate Change in Africa. However, the paper was still great and informative. Thank you!

I finished the first deliverable of a project presentation but had no time to finish my second deliverable. The writer revamped my first deliverable and made it much more appealing! Not only was I impressed with the content but I was so grateful for the time they took to redo the background. I have been under a lot of pressure at work and at home so this has been a great service when I have had little time! I appreciate the detail and help! Always on time and always exceeding expectations!
