C ++中的多个输入和输出

Question

我有一个用C ++ 17编写的代码，将值x和y作为输入，并提供一些值作为输出。我想更改它以接受尽可能多的输入（x和y值）并给出输出。需要在代码中进行哪些更改

代码中发生的事情是：使用一些x和y坐标，它会找到坐标号。

#include <iostream> 
#include <vector>
#include <utility>

constexpr double CellWidth = 340.0; 
constexpr double CellHeight = 320.0; 
constexpr double OffsetLeft = 220.0;
constexpr double OffsetTop = 200.0;

constexpr double SpaceHorizontal = 608.0;
constexpr double SpaceVertical = 500.0;

constexpr unsigned int TileNumberOfRows = 17u; 
constexpr unsigned int TileNumberOfColumns = 10u;
constexpr unsigned int NumberOfTilesHorizontal = 2;
constexpr unsigned int NumberOfTilesVertical = 2;


struct Tile {
    Tile(unsigned int tn);
    std::pair<bool, unsigned int> getCellNumber(const double x, const double y) const;   

    unsigned int tileNumber{};

    double posLeft{};
    double posTop{};
    double posRight{};
    double posBottom{};
}; 

// tielnumer starting with 0. From left to right, then next row
Tile::Tile(unsigned int tn) : tileNumber(tn)   
{

    // Calculate the index of the tile
    unsigned int tileIndexX = tileNumber % NumberOfTilesHorizontal;
    unsigned int tileIndexY = tileNumber / NumberOfTilesVertical;

    // Calculate X position of tile
    posLeft =
        // Left margin to paper
        OffsetLeft  - (CellWidth / 2.0) 
        + tileIndexX * (
            // Tile Width
            TileNumberOfColumns * CellWidth +
            SpaceHorizontal - (CellWidth / 2.0)
            );


    posTop =
        OffsetTop  - (CellHeight / 2.0)    
        + tileIndexY * (
            TileNumberOfRows * CellHeight +
            SpaceVertical - (CellHeight / 2.0));

    // Right position of tile
    posRight = posLeft + TileNumberOfColumns * CellWidth;

    // Bottom position of tile
    posBottom = posTop + TileNumberOfRows * CellHeight;

}



// Check, if in pos is in tile and at what position
std::pair<bool, unsigned int> Tile::getCellNumber(const double x, const double y) const

{

    unsigned int cellNumber{ 0 };
    // Is the position in range of this tile?
    const bool inTile{ (x >= posLeft) && (x <= posRight) && (y > posTop) && (y < posBottom) };

    // If so
    if (inTile) {

        // Calculate row in local tile
        unsigned int col = static_cast<unsigned int>((x - posLeft) / CellWidth +
            ((tileNumber % NumberOfTilesHorizontal) * TileNumberOfColumns));

        // Calculate col in local tile
        unsigned int row = static_cast<unsigned int>((y - posTop) / CellHeight +
            ((tileNumber / NumberOfTilesVertical) * TileNumberOfRows));

        // And now calculate the overall cell Number
        cellNumber = row * TileNumberOfColumns * NumberOfTilesHorizontal + col;

    }
    return std::make_pair(inTile, cellNumber);
}



int main(void) {
    const std::vector<Tile> tiles{ Tile(0),Tile(1),Tile(2),Tile(3) };

    // Test values
      const double  x{ 3700 };  // want to  add multiple entries here
      const double  y{ 11261 };  // want to  add multiple entries here

    // Check cell number
    for (const Tile& tile : tiles) {
        if (const auto [isInTile, cellNumber] = tile.getCellNumber(x, y); isInTile) {
            std::cout << "
Cellnumber: " << cellNumber << "
:)





";

        }
    }


    return 0;
}

我已经尝试了许多更改，但是总是以某些错误结尾，而且我对C ++还是陌生的，主要语言是python。
