I wrote this code: #include<vector> using namespace std; int i; int j; cin>>i>>j; vector<vector<vector<vector<double>

I wrote this code:

 #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))));

During compilation the following error came up:

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> >)’

    Your initialization line is wrong. It should be more like this:

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