Will It Compile?

[snazziosity]

Will this program compile on Windows? I need to turn in a project that compiles on Windows (specifically, Visual C++) for a class I'm taking. However, I am a Mac/UNIX user (please don't shoot me!) and I have been compiling and running programs in Terminal since I started learning to program two years ago, never using Windows to do so. I don't have a working Windows computer at my house, and I have no idea how to compile my project on a school computer. The program runs fine on my Intel-based Mac, but I know there are differences when you try to run it on a Windows computer.

The program reads in a text file containing a poem to an array. You can then delete words starting with a specific letter and print the array. At the end, it will make a text file containing what remains in the array.

Will someone please compile and run this program on their Windows computer so I can be sure that my instructor will be able to run it?

Thank you so much!

so much depends
upon

a red wheel
barrow

glazed with rain
water

beside the white
chickens.

Thank you!

It compiles fine but output is not valid:

Please make a selection:
a) Read a text file
b) Remove words starting with letter
c) Print words to console
d) Quit
-> a

Enter a filename to open: sample.txt
Loaded file and read 15 words.

Please make a selection:
a) Read a text file
b) Remove words starting with letter
c) Print words to console
d) Quit
-> c

This is because strlen returns length of a string without the null character.

Word::Word(const char* word)
{
    len = strlen(word)+1; // length of the string + 1 null ('\0') character
    ptr = new char[len];
    memcpy(ptr, word, len);
}

Word::~Word()
{
    delete[] ptr; // free unused memory
    ptr = NULL;
    len = 0;
}

You also need to #include <cstring> instead of <string> in word.cpp, and remove using namespace std; from word.h
