Question

create a vector of MYStrings that is size 100 read each of the words from the file called "infile2.txt" (the file is out in Files section under Program Resources). You can call the read function directly on the indexed vector. (do not use vector's push_back function. See programming note below*). Example: while ( words[count].read(fin) ) {...} as you are reading the words in, keep a count of how many words were read in. After you have read in all the words from the file, resize your vector to the correct size based on your count of the number of words read in. sort the MYStrings from smallest to largest (this will be based on the ASCII encoding....meaning capital letters will sort before lower case letters) using Bubble Sort output the sorted words to outfile.txt file 6 words per line ( use setw(13), which is part of library, to space them out....the setw command should not be in the write member function). Below is an example of what you output should look like .....but is missing the middle section.
