In C++, there are multiple ways to initialize and assign values to an array. Here are some commonly used methods:<\/p>\n

    \n
  1. Initialize the list using parentheses.<\/li>\n<\/ol>\n
    int<\/span> arr[] = {1<\/span>, 2<\/span>, 3<\/span>, 4<\/span>, 5<\/span>};\r\n<\/code><\/pre>\n
      \n
    1. Assign values one by one using a loop.<\/li>\n<\/ol>\n
      int<\/span> arr[5<\/span>];\r\nfor<\/span> (int<\/span> i = 0<\/span>; i < 5<\/span>; i++) {\r\n    arr[i] = i + 1<\/span>;\r\n}\r\n<\/code><\/pre>\n
        \n
      1. Copy the values of another array to the target array using the memcpy function.<\/li>\n<\/ol>\n
        int<\/span> source[] = {1<\/span>, 2<\/span>, 3<\/span>, 4<\/span>, 5<\/span>};\r\nint<\/span> destination[5<\/span>];\r\nmemcpy<\/span>(destination, source, sizeof<\/span>(source));\r\n<\/code><\/pre>\n
          \n
        1. Use the fill function to set all elements of the array to a specific value.<\/li>\n<\/ol>\n
          int<\/span> arr[5<\/span>];\r\nstd::fill<\/span>(arr, arr + 5<\/span>, 0<\/span>);\r\n<\/code><\/pre>\n
          Please note that there are other more convenient methods for initializing arrays introduced after the C++11 standard, such as using brace initializers and the std::array container.<\/p>\n","protected":false},"excerpt":{"rendered":"
