CString 找到最后一个条目
我有两个 CString s1 和 CString s2.我需要在 s1 中找到最后一个条目 s2.我可以在 CString 中找到任何方法，例如在 C# LastIndexOf 中.我是 C++ 中的菜鸟.提前致谢.
I have two CString s1 and CString s2. I need find the last entry s2 in s1.
I can find any metod in CString like in C# LastIndexOf.
I am nooby in c++. Thanks in advance.
推荐答案
CString 没有这个功能.你必须自己写，例如
CString has no such function. You have to write it yourself, e.g.
int LastIndexOf(const CString& s1, const CString& s2)
{
int found = -1;
int next_pos = 0;
for (;;)
{
next_pos = s1.Find(s2, next_pos);
if (next_pos == -1)
return found;
found = next_pos;
};
}
一种更优化的算法会首先反转字符串，我将其留作练习.
A more optimal algorithm would reverse the strings first, I'm leaving that as an exercise.
