In C++, there are several methods to create a two-dimensional array:<\/p>\n

    \n
  1. You can create a two-dimensional array by specifying the number of rows and columns using array declaration syntax. For example:<\/li>\n<\/ol>\n
    int<\/span> array[3<\/span>][4<\/span>]; \/\/ \u521b\u5efa\u4e00\u4e2a3\u884c4\u5217\u7684\u4e8c\u7ef4\u6574\u6570\u6570\u7ec4<\/span>\r\n<\/code><\/pre>\n
      \n
    1. fresh<\/li>\n<\/ol>\n
      int<\/span> **array;\r\nint<\/span> rows = 3<\/span>;\r\nint<\/span> cols = 4<\/span>;\r\narray = new<\/span> int<\/span>*[rows]; \/\/ \u5148\u5206\u914d\u884c\u6570<\/span>\r\nfor<\/span> (int<\/span> i = 0<\/span>; i < rows; i++) {\r\n    array[i] = new<\/span> int<\/span>[cols]; \/\/ \u518d\u5206\u914d\u5217\u6570<\/span>\r\n}\r\n<\/code><\/pre>\n
        \n
      1. a quantity that has both magnitude and direction<\/li>\n<\/ol>\n
        #include<\/span> <vector><\/span><\/span>\r\n...\r\nint<\/span> rows = 3<\/span>;\r\nint<\/span> cols = 4<\/span>;\r\nstd::vector<std::vector<int<\/span>>> array<\/span>(rows, std::vector<\/span><int<\/span>>(cols));\r\n<\/code><\/pre>\n
        In these methods, using array declaration syntax and dynamic memory allocation both require determining the number of rows and columns beforehand, while using vector containers allows for dynamically adjusting the size of the array.<\/p>\n","protected":false},"excerpt":{"rendered":"
