c - WCHAR [256] as WCHAR ** 即，迭代数组字符串与仅迭代一个字符串

Question

我正在编写一个代码，我想在其中迭代字符串数组。但有时我可能只需要迭代一个字符串，而该字符串的形式为 WCHAR[256] 现在问题是如何将 WCHAR[256] 视为 LPCWSTR* 以便我不必处理 WCHAR[256]作为迭代时的特殊情况。下面是代码示例。

请告诉我这里是否还有其他优雅的解决方案？

WCHAR BranchName[MAX_PATH];
BOOLEAN AllBranches;

WCHAR* DefaultBranches[] = {
    L"branch1",
    L"branch2",
    L"branch3",
};

INT
wmain (
    _In_ INT Argc,
    _In_ WCHAR **Argv
    )
{

    WCHAR **Branch; // Pointer to array of strings. How can I make this point to WCHAR[256]?
    UINT Count;
    UINT Index;

    ParseArguments(Argc, Argv); // Set AllBranches to true if Custom branch is not provided

    if (AllBranches) {  // If all branches is true
        Branch = DefaultBranches;
        Count = ARRAYSIZE(DefaultBranches);
    } else { // BranchName containing the custom branch name provided as cmd line arg
        // How can BranchName be assigned to Branch pointer so that iterating
        // over just one string do not become a special case?
        Branch =  ???  <-- NOT SURE HOW TO DO IT!!!
        Count = 1;
    }

    // I want this loop to iterate over array string pointers and also with
    // one string
    for (Index = 0; Index < Count; Index += 1) {
        // do some thing with *Branch and I don't want to duplicate it
        // when iterating over array of strings vs iterating over a string
        Branch++;
    }

    return 0;
}

要么

WCHAR * BranchNameArr [] = { BranchName };
Branch = BranchNameArr;

或

WCHAR * BranchNamePtr =  BranchName;
Branch = & BranchNamePtr;

还好。
