Hello everyone, this is my third post for help for my Programming Meth Class. My class has gotten a problem in Lab where only 3/the entire class figured out. It's due Sunday and I just don't know what to do. Well I should say I don't have time to do it because I have an exam on Sunday plus this assignment being due right after the exam, but can anyone give me help or teach me how to merge these arrays. My program looks like this. I don't want anyone to fiddle around with the main function. I just don't know what to do in the void merge function. Also we are supposed to use strcpy and strcmp functions. I looked on google on how to merge arrays but they do it without the functions. Can anyone help??? Much appreciated and would help this future engineer out a lot.
