4 year graduation required total credits

Can someone please let me know what is the yearly total credits and a complete 4 year credits that are required for graduation from UPitt?

My D was comparing computer engineering Major vs computer science Major course credits for UPitt.
either D missed counting some general classes credits or maybe there is a huge difference in the credits earned through engineering school and computing school.
Does Computer science major (not engineering) itself have enough credits to graduate with a 4 year degree?

how difficult is it for a student to change majors from engineering to computing or vice versa?

How to enroll for a dual enrollment (minor) in different school while applying for a major in school of computing or engineering?
