Custom C/C++ Headers with Eclipse

One of the great things in Eclipse is that it can be customized down to the bits. The downside (pun intended) is that it might not be obvious how to do this. So here is how you can create your own custom file header when creating a new C/C++ file in Eclipse:

Error for ‘implicit function declaration’ Warning in C

“A young man is smoking one cigarette after each other without a pause. An elderly woman observes that and says: “Young man, you are smoking like crazy! Don’t you know that there is a warning on each cigarette package that this can kill you?” The young man finishes his cigarette, looks at the elderly person and says: “Yes, I know. But look, I’m a programmer, and it is only a warning.”

I don’t smoke, and I do pay attention to warnings :-). I always try to keep my source code free of compiler warnings. And I always pay special attention to the following on:

Optimized and Easy-to-Use Eclipse Toolbars and Menus

Or in general ways: how to use symbols defined in the linker script accessible in the C source code.

Engineering Joke of the Week: The Pet Shop

A tourist walked into a pet shop and was looking at the animals on display. While he was there, another customer walked in and said to the shopkeeper: “I’ll  have a C-monkey please”.

The shopkeeper nodded, went over to a cage at the side of the shop, and took out a monkey. He fit a collar and leash and handed it to the customer, saying “That’ll be $5000”.

The customer paid and walked out with his monkey.

Startled, the tourist went over to the shopkeeper and said: “That was a very expensive monkey, most of them are only a few hundred dollars. Why did it cost so much?”
