why we use letter 'm' for variable decleration

[jamilsh]

I have seen lot of C/C++ code but couldn't understand why we use letter
'm' with lot of variable declaration. See example below.

private:
static NXTSTRUCT_t mTaGat;
static DDXYZSTRUCT_t mEditGat;


Thanks,

It indicates that it's a member variable. Personally I find it ugly. YMMV.

For the same reason the letters "_t" are in the types.

m is for member variable of a class or a structure.

There's no requirement by the language that this be done,
but it could be part of a business' coding standards, and
some folks adopt it as their personal 'style', ('m' used
to denote 'member' (of a class) ).

It's a 'style' issue.

Those are incorrect because m_ should denote a member. ("Should" applies
when your team or teacher decide which decorations they want to use for a
given project.)

They should be sm_, for Static Member. Other variations:

g_ global
s_ file static
s or str string
p pointer
a or the reference

These are _not_ Hungarian Notation, which Google can easily tell you why it
sucks, so PLEEEEZE don't start a thread.
