no suitable conversion function from "std::basic_string <char, std::char_traits<char>,std::allocator<char>>"to "int" exists

My code is unfinished at the moment but the problem I'm having is the "name" of if(isspace(name[j].substr(i, 0} is giving me the error no suitable conversion function from "std::basic_string <char, std::char_traits<char>,std::allocator<char>>"to "int" exists

A substring is still a string, and that's not what is expected by isspace().

Replace name[j].substr(i,0) by name[j][i] on line 101 if you want a single char.

No idea what you are trying to do in that routine, though.

"std::basic_string <char, std::char_traits<char>,std::allocator<char>>" is just the templately "behind the curtain" type that a string really is.

So the error is actually: Cannot convert string to int.

As lastchance said, you want name[j][i] most likely. Note that the substr(i, 0) call doesn't make sense anyway, because you are saying the length of the substring is 0, which can only be an empty string.

Also note that passing vector<> by value (as here) causes an extra copy of the whole vector. Pass by const ref if not changed, or by ref if changed.
