警告 C26496

仅分配一次变量 “variable”，请将其标记为 const。

另请参阅

C++ Core Guidelines con.4。

示例

int GetTheNumber();
int GiveMeTheNumber(int);

void function1()
{
    int theNumber = GetTheNumber(); // C26496, 'theNumber' is never assigned to again, so it can be marked as const
    std::cout << theNumber << '\n';

    GiveMeTheNumber(theNumber);
    // ...
}
