It has been modified according to others' results. The problem to be noted is that the parameter is not const, so it can be modified.
C++ determines whether the specified directory exists
bool IsDirExist(string filename)
{
size_t len = filename.length();
if(filename[len-1] != '/' && filename[len-1] != '\\')
filename.append("/");
filename.append("000.tmp");
ofstream outf(filename.c_str());
bool flag = outf;
if(outf)
{
outf.close();
remove(filename.c_str());
}
return flag;
}
