[Dev-C++] declaring a integer vairable

[Gerald H. <gl...@we...>]

Hi all

I have been on a couple of c++ websites. Some of them say to declair an 
interger vairable you will you this code.

int var1;
int vartest;

And some of them say this

int 1;
int test; 

Which one is correct do you have to use that var.

Regards
Gerald

First of all - never add a prefix "var" or similar that doesn't mean
anytning.

Second - a variable name may contain digits, but it may not start with a
digit, so "1" is not a valid variable name.

When declaring variables, always make sure that their names describes the
variable function in a good way, i.e.

int number_of_customers;
int remaining_attempts;
int kilobytes_transmitted;
int customer_idx;
...

Then you can read your source code two years from now, and understand what
it does.

A variable named "test" doesn't give much information about it's use. You
might possibly be testing something, but testing what?

I concur.  C/C++ can be self-documenting if you follow Per's advice. 
Otherwise it can be the most inscrutable code to understand and debug.

I've had the two year problem, BTW!
