I am trying to figure out the merge sorting. I have searched the Dani and found other examples but they did not help me. I wanted to figure it out by myself but I cant.
here are my Errors :


Error 3 error C2446: '<' : no conversion from 'int' to 'int []' c:\users\phil\desktop\c++\cs230\lab6\lab6\lab6\lab6.cpp 150
Error 4 error C2040: '<' : 'int []' differs in levels of indirection from 'int' c:\users\phil\desktop\c++\cs230\lab6\lab6\lab6\lab6.cpp 150
Error 5 error C2446: '<' : no conversion from 'int' to 'int []' c:\users\phil\desktop\c++\cs230\lab6\lab6\lab6\lab6.cpp 150
Error 6 error C2040: '<' : 'int []' differs in levels of indirection from 'int' c:\users\phil\desktop\c++\cs230\lab6\lab6\lab6\lab6.cpp 150
