Template with Inheritance C++ -
using inheritance , templates, ive sort name array of employee information. got 3 classes, payroll, simplevector , sortingvector. payroll contains user info attributes, simplevector creates dynamic array of type payroll store user info. sortingvector class in charge of sorting array names. keep getting many different errors whenever tried fix previous error.
posting each class:
payroll class

sortingvector<payroll> temp(); not parsed expected (vexing parse), want:
sortingvector<payroll> temp; or
sortingvector<payroll> temp{}; /* since c++11 */
