Write a C++ Program that:

Uses strings

Passes strings to functions

Uses file I/O.

Project Requirements:

1. Write a function that, given two strings as input, checks if one string is a substring of the other. If so, capitalize the substring and print the new capitalized string.

For example: If the input is Begin and in. Then we must check if any of these strings is a substring of the other. If yes print a statement as below.

Yes, in is substring of Begin

Now capitalize the substring and write the new capitalized string to a new file specified by the user. The new string for the above example is BegIN. You should ignore case when comparing strings; that is, given Hilly and hill as input the function should still find hill to be a substring of Hilly.

2. Read the words (strings) from a file the user chooses in main() and write the new strings to another file of the users choice.

3. You have a few choice in implementation:

Use of either old style c-strings (character arrays) or the string (#include ) class.

Use of a data structure (array or vector) to store the strings. You can store the strings in such a container, or you can just read and write them without using storage.

Sample

Please enter the input filename: input.txt

Please enter the output filename: output.txt

The original strings are:

String

Ring

Ring is a substring of String

The new string is: StRING

Content has been written to the file output.txt.
