c++ 2D vector push_back error in code - c++

Question

I had my program working with a single vector and decided to use a 2D vector to represent multiple hands (one dimensional vector vPlayerHand1 plus one dimensional vector vPlayerHand2 plus ...). I can't figure out how to populate the vector. I am using Visual Studio C++ 2010 which does not seem to fully implement C++11 and reports parsing errors in the IDE for code that is provided as answers to similar questions in this forum. In the outline below Card is a class.
#include <vector>
std::vector<std::vector<Card>> vPlayerHand;
vPlayerHand.push_back(vShoe.back()); /* fails with parsing error No instance of
overloaded function... */
vPlayerHand[0].push_back(vShoe.back()); /* builds okay then error Debug Assertion
Failed... vector subscript out of range */
I am missing something on the correct use of the push_back function with a 2D vector (vector of vectors) I understand the first reference is to the row. and when I populate with push_back it should just do the first row.
Here is more complete code:
Edited at line 29... code runs correctly as given
Re-edited at line 32a as per solution by #RSahu runs correctly. Commented out line 29
1 # include <iostream>
2 # include <vector>
3 # include <algorithm>
4 # include <ctime>
5 # include "Card.h" //Defines Card as having Suit, Rank and functions GetSuit() GetRank()

7 std::vector<Card> vShoe; //Card Shoe vector holds 1-8 decks
8 std::vector<Card> vDeck; //Deck vector holds 52 cards of Card class
9 std::vector<std::vector<Card>> vPlayerHand; // Player Hands 0-original, 1-split1, n-splitn
10 std::vector<Card> vDealerHand;
11
12 void CreateDeck(); //Populates Deck with 52 Cards
13 void CreateShoe(int); //Populates Show with Decks*n number of Decks
14 void ShuffleShoe(); // uses random_shuffle
15
16 int main() {
17
18 int iDeckCount = 2;
19 const int NumPlayers = 1;
20 srand(time(0));

22
23 CreaateDeck();
24 CreateShoe(iDeckCount);
25 ShuffleShoe();
26
27 // Following line gives parsing error
28 // vPlayerHand = std::vector<std::vector<Card>> (5, std::vector<std::vector<Card>>(12));
// added this line and now runs as expected
/* removed this line in favor of line 32a as per #RSahu
29 vPlayerHand.resize(2); // need only initial size for 2 elements
*/
30 for (int i=0; i<=NumPlayers; i++) {
31 // I believe this is where dimension error comes vPlayerHand[0].push_back
32 // I tried vPlayerHand.push_back(vShoe.back()) but get parsing error "No instance of overloaded function.."
// This line added as per R Sahu. compiles and runs correctly
32a vPlayerHand.push_back(std::vector<Card>());
33 vPlayerHand[0].push_back(vShoe.back()); //Top card in Shoe (last card in vector) is dealt to Player
34 vShoe.pop_back(); //Top card in Shoe is removed (destroyed) from vector Shoe
35 vDealerHand.push_back(vShoe.back()); //Top card in Shoe (last card in vector) is dealt to Dealer
36 vShoe.pop_back(); //Top card in Shoe is removed (destroyed) from vector Shoe
37 }

Any insight would be helpful.

You have defined vPlayerHand as:
std::vector<std::vector<Card>> vPlayerHand;
When you use vPlayerHand.push_back(arg), arg has to be of type std::vector<Card> or convertible to std::vector<Card>. An argument of type Card cannot be used as an argument to that function. That's what you are trying when you use
vPlayerHand.push_back(vShoe.back())
What you need is:
vPlayerHand.push_back(std::vector<Card>());
vPlayerHand.back().push_back(vShoe.back());
vShoe.pop_back();
vPlayerHand.back().push_back(vShoe.back());
vShoe.pop_back();
