I am a professional C++ programmer. I have been programming in C++ as a Windows Desktop developer since 2001. I am just starting out in as a freelance developer now
I do have some questions concerning your project:
Are you programming in a Windows based environment, Unix or Linux?
Are you allow to your functions from the Standard Template Library or do you have to create StringInsert(), Stringclean(), and StringCase(') from scratch?
What exactly do these functions have to do? What are their parameters, if any? I can guess from the names of the functions. However, I want to be very sure exactly how these functions are supposed to perform so I can create the best behavior for you.
You can contact me through my Freelancer chat to give me more information.
I hope to hear from you soon.
