美好的一天..我需要一些与此C ++代码有关的帮助，因为这些错误是:

C:\ Program Files \ Microsoft Visual Studio \ MyProjects \ payroll daw \ payroll nga daw.cpp(64):警告C4508:"main":函数应返回值；假定为"void"返回类型

和


C:\ Program Files \ Microsoft Visual Studio \ MyProjects \ payroll daw \ payroll nga daw.cpp(149):错误C4716:``payroll :: get_info'':必须返回一个值


任何愿意帮助的人..

非常感谢..

推荐答案

"<< pay; cout<< " ; cout<< "

" << pay; cout << "\n\n"; cout << "\nEmployees SSS deduction is :

" << ; sss; cout<< " ; cout<< "

" << sss; cout << "\n\n"; cout << "\nEmployees Philhealt deduction is :

" << ;菲尔 cout<< " ; cout<< "

" << phil; cout << "\n\n"; cout << "\nEmployees Total deduction is :
