Hungarian notation

Im curious what your opinion on Hungarian notation is. It seems most C and C++ programmers dont like it, but I dont see why, it seems like a practical thing to do, especially to know which variables are pointers.

Would you look at that, meaningful variable names! I just name my variables _GXXX, where the XXX stands for a number that's 0 for the first variable and is auto-incremented with each subsequent one.
