如何获得最后一笔？

Question

I want to split a "string" (delimiter \\ ) to get the last occurrence. This is the code I wrote:

char str[] ="D:\\Google Drive\\My Files\\Test.zip";
char * buffer = str;

sprintf(buffer, "%s", strtok(str,"\\"));
cout << buffer;

but it returns D: instead of Test.zip (the first occurrence, not the last). How would you do this task?

I need to use/keep sprintf (ie format string approch).

Answer 1

Use strrchr instead - it's more appropriate in this context, and both non-destructive and reentrant too:

char str[] ="D:\\Google Drive\\My Files\\Test.zip";
char * buffer = strrchr(str, '\\');
cout << buffer + 1;

If you really do have to keep the redundant and inefficient use of sprintf as per your question then you can of course do this:

char str[] ="D:\\Google Drive\\My Files\\Test.zip";
char buffer[256];
sprintf(buffer, "%s", strrchr(str, '\\') + 1);
cout << buffer;
