Question

Write a program that reads from the external file input.txt, capitalizes all words that begin with the letter "a," and then writes them to an external file output.txt (Note: Do not forget to copy the blanks. You may wish to use infile.get and outfile.put in your program.) Output: After the program generates output.txt, the code should display the contents of the file on the screen to verification.
