Question

我写了这段代码：

 #include<vector>
 using namespace std;
 int i;
 int j;
 cin>>i>>j;

vector<vector<vector<vector<double> > > > boy_max(i,vector<double>(i,vector<double>(j,vector<double>(j,0))));

在编译过程中出现以下错误：

prog.cpp: In function ‘int main()’:
prog.cpp:164: error: no matching function for call to ‘std::vector<double, std::allocator<double> >::vector(int&, std::vector<double, std::allocator<double> >)’

您的初始化行错误。应该更像这样：

vector<vector<vector<vector<double> > > > boy_max(i,vector<vector<vector<double> > >(i,vector<vector<double> >(j,vector<double>(j,0))));
