Question

Hello I am just trying to get a little nudge in the right direction

I cant make it into the lab due to work.

/*
Complete insertStudents and deleteStudents functions in the skeleton program.

The output of the program should be like:

sid=001,name=John
sid=002,name=Joan
sid=003,name=Jack
sid=001,name=John
sid=003,name=Jack
