Getting string out of a 2D vector into a string variable

[AdRock]

I have a 2D vector and I need to assign each value of the inner vector to a string.

I am having problems getting what is in the vector into a string variable

If anyone could please help I would be very happy as I can't fix this problem

for ( vector< vector< string > > :: size_type i = 0, size = info.size(); i < size; ++i)
{
	for ( vector < string > :: size_type j = 0, length = info[i].size(); j < length; ++j)
	{
		//check to see if the inner vectors are empty
		if(info[i].size() > 1)
			
			//std::string strd = info[i][j].at(j);
			//cout<<strd.c_str()<<endl;
			//if(strd == "int") {cout << "INT: ";}
			cout << info[i][j] << endl;
	}
	cout << endl;
}

for ( vector< vector< string > > :: size_type i = 0, size = info.size(); i < size; ++i)
{
    for ( vector < string >:: size_type j = 0, length = info[i].size(); j < length; ++j)
    {
            string strd = info[i][j] ; // this will do 
            // equivalent to 
            // vector< string >& inner_vec = info[i] ;
            // string strd = inner_vec[j] ; 
            cout << strd << endl;
    }
    cout << endl;
