I've just recently started learning c++. I'm currently working on a simple calculator which allows the user to input into a char array. I was wondering if anyone could point me in the right direction to figure out how to add command line editing functionality. What library and/or what function could I use? Thanks in advance.

You can process command-line arguments using C++ as follows: #include &ltiostream.h> int main (int argc, char **argv) {    cout &lt&lt "Received " << argc << " arguments...\n"; for (int i=0; i < argc; i++) {    cout << "argument " << i << ": " << argv[i] << endl; } return 0; } Infinite Recursion

Of course my reference to the '& l t' is a less than character... not sure what happened on that. At any rate, that code will give you access to command-line arguments. Infinite Recursion

I think you misunderstand. Perhaps I did not explain it properly. I'm not wanting to process command line arguments. I want to allow a user to edit their input before pressing enter. They should be able to use the arrow keys to go back and change parts of their inputs instead of using backspace and deleting part of the input. Just like command line editing in bash.
