Compile Error with GCC 4.2.1/6.2.0 and the solution

[SymenYang]

There are some errors in codes which will cause compile error. I tried GCC 4.2.1 and 6.2.0 and will both get the problems. This problem caused by 2 code errors.
First is the 2D STL-Vector initial commands. change the code
std::vector < std::vector<SOMETHING> >( size1 , size2 )
into
std::vector < std::vector<SOMETHING> > ( size1 , std::vector<SOMETHING>(size2) )
Second is the output part. In main.cpp, use "%s" to output a String value instead of Char* may cause problem. Also the "void main()" should change to "int main()" and add "return 0"
