Hey everyone, I am writing a program for my c++ class to take student records and organize them according to the students last name. All data is stored to a class and I have created an array of class objects(its part of the assignment). I am using Vi to compile (again because I have to) and here are the compile errors I'm getting:
assign5.cpp: In function âint main()â:
assign5.cpp:83: error: too many arguments to function âvoid Sort(cStudent (&)[30], int)â
assign5.cpp:92: error: at this point in file
assign5.cpp: In function âvoid Swap(cStudent (&)[30], cStudent (&)[30])â:
assign5.cpp:137: error: invalid array assignment
assign5.cpp:138: error: invalid array assignment
assign5.cpp:139: error: invalid array assignment
assign5.cpp: In function âvoid Sort(cStudent (&)[30], int)â:
assign5.cpp:149: error: argument of type âvoid (cStudent::)(char (&)[11])â does not match âconst char*â
assign5.cpp:151: error: invalid initialization of reference of type âcStudent (&)[30]â from expression of type âcStudentâ
assign5.cpp:134: error: in passing argument 1 of âvoid Swap(cStudent (&)[30], cStudent (&)[30])â

thanks!
