Hi
I am integrating my program into using different Classes. I have been trouble shooting for a while and I am stuck on this error and I don't understand the problem even reading online. I am using two Specification files with no Implementation files. I just want to make it easier with less files. I have one header file for working with read and write file. Another header file to work with add, sort, delete and display content of the vector DirV[].
This is fileManage.h for read and write to file.
This is vectorEdit.h for add, delete, sort and display content of vector DirV[].
This is the main():
I have been working on the integration since yesterday. This is really pushing beyond my knowledge. I spent 3 hours troubleshooting just to find I missed a ';' at the very end of the header file! The error showed was "using namespace std;" in main() doesn't work and I had to put std:: on every single cout, cin, setw(), left, right!The error messages are:
What is error C3867? I read on line and I don't understand. I don't know what I did wrong.
Please help. Also please comment on how I write the program. First time doing this, no idea whether this is right or not. I know I have to split up the vectorEdit.h as it's very long.
Thanks
