So I am trying to initialize a 2D vector of pointers/matrix of pointers(/3d vector?) in c++. A 2D matrix of pointers to cell objects. When running the code I get this error: error: no matching function for call to ‘std::vectorstd::vector<Cell* >::push_back(std::vector&)’ 17 | matrix.push_back(temp); Note:Cell is a class City.hh: std::vector <std::vector <Cell*>> matrix; City(unsigned int ..

I’m creating text based TicTacToe in c++ and need to create a function that checks for a win. Right now I have a vector of all the moves player X has made. std::vector<int> x_vector = {1, 2, 3, 5, 7}; I also have a 2d vector of win conditions. std::vector<std::vector> > wins = {{1, 2, ..

I need to have a function in c++ that gets an element from a vector of strings as soon as the input is unique. For example, my vector contains {"DELETE", "HELP", "GO FORWARD", "GO BACKWARDS"}. If my input is then "H", the function should output "HELP" If the input is "H 55", it should ignore ..
I need to overwrite values in a 2D vector, where the new values is simply just equal to an integer I am counting up. But as soon as I exit this if-statement, the value resets to the original value? I think it may have something to do with the indexing, but I just can’t figure ..
I am trying to create a 10 by 10 grid with uint8_t values. using some coordinates I am trying to place 255 values at those indexes. When I substitute 255 at those coordinates it works fine but as soon as I try to print out the values at those indexes it doesn’t seem to be ..
I was creating empty 2D vector in a header file by just providing size but unable to create it. class Grid { public: int rows = 5/0.05; int cols = 6/0.05; std::vector<std::vector<uint8_t>> grid(rows, std::vector<uint8_t>(cols, 0)); }; I am getting below error no matching function for call to ‘std::vector<std::vector >::vector(int&, std::vector)’ error: ‘rows’ is not a ..
I have a 2D vector of Integer and want to count how many times certain value is repeated. For example: I have myvector defined as: std :: vector <std :: vector <int>> myVector {{{1, 2, 9, 4, 6}, {8, 3, 5, 4, 8}, {4, 1, 9, 1, 7}, {5, 2, 7, 3, 4}, {7, 4, ..
I have a simple ball class. It takes a color name for its initialization. Ball::Ball(ColorName color_name) : m_color_name{color_name} { } I try to create a 2d-vector board to contain some balls. The width and the height are given outside. class Board { private: int m_width; int m_height; std::vector<std::vector<Ball>> m_grids; public: Board(int width, int height); ~Board(); ..
I am trying to take values in a 2d vector called alloc from the user but the alloc zero index is the only changed index and the values of each index override it i don’t know why (i.e: only the first index of the 2d vector is affected) Code: cout<<"Please Enter n"<<endl; cin>>n; cout<<"Please Enter ..
