Reverse char array completely confused

Hey everyone, I am trying to complete an assignment and I am super confused and cannot get this function to work. I am trying to reverse a char array.
I am successfully able to reverse the string: cytogeneticists to tsicitenegotyc
but there is no output from the function when word[3] is passed in or "Bolton"
same for word[4]. Any tips to solve this is very much appreciated. Thanks
Here is the code:

// Test the reverseCopy function

Some part of the code are missing, I can't find your main

By the way

int wait;
cin >> wait;

you may use
system("pause");
