C++ is responsible for this.

C++ made the usage of 'this->' optional when calling member functions.

As a result, when C++ programmers encounter 'i' in the middle of a 
function, they might not know where it comes from.

If 'this->' were not optional, 'this->i' would clarify that.

To avoid confusion, many C++ programmers use prefixes like 'm_' that 
can't be ignored.

Since many C programmers also work in C++, this pattern can sometimes 
influence C code as well.
