String manipulation

int Sz=strlen(MyString);
*(int *)(MyString+Sz-4)='pmb.';


:P

[Edit]
If you're wanting to just use C, then you could use strrchr() to find the last '.' in the string, and strcpy() to copy the new extension over the old one.

//Disclaimer NOT [thoroughly] TESTED!!!char FileName[256];strcpy(FileName, "c:\\animations\\anim1.avi");strcpy(strrchr(FileName, '.'), ".bmp");

It's not inherently memory-safe, though, as is the case with many C string manipulations.

If you're using C++, though, and don't mind using std::string, then you can do it pretty easily. If you know that the two extensions are the same length, as in the example, then this simplifies things even more.

//Disclaimer: [also] NOT [thoroughly] TESTED!!!std::string FileName;//If you're not guaranteed to have equal size extensions:FileName = "c:\\animations\\anim1.avi";FileName = FileName.substr(0, FileName.rfind('.')) + ".bmp";//If you are guaranteed to have equal size extensions:FileName = "c:\\animations\\anim1.avi";FileName.replace(FileName.rfind('.'), 4, ".bmp");

The second one should be more efficient, but the first is more reliable, since it works on any extension.

@Empirical: That's insane[ly clever]. [wow][smile]

Sorry for the late reply, but thanks guys. The code works perfectly.
