c++, tips

In last 2 yeas i have worked a lot on C Programming But now days i need to work on C++ and Java programming language. I have not time to take book of C++ or java programming and start to read that…In any programming language most of the stuff are common. So you know one language very well then by keeping that in mind you can learn other language very well.

Some days ago i found this article and it helped me a lot. i hope this will also help you….

Sometimes we need to write platform independent code which works in windows and linux machine without giving any flag or any modification in code or make file manually.

So in such case i usually use compiler generated macro to check the platform .

In Linux all c and c++ compiler define macro like linux, In Windows all c and c++ compiler define macro like _WIN32

so we can use this macro to separate code for linux and windows see belows example code

c, sample programme Tags

After a long time, I am back. Months without programming and then finally I got some time on my hands. So I set out to code the Huffman’s Data Compression Algorithm. And the result is here!

The code is well-commented and I hav given some additional documentation. Also, I hav tested it extensively – right from small words to complete bollywood Songs..:P

Here i had did two types of Huffman Encoding

1 ) Simple User Input

2) Take Input from File

But if there are any probs,let me know.

Valgrind

One more tips for c-programmer,embedded software engineers.

In many case you need to make sure that your programs is not going to leak any heap memory.
In Manny case while debugging code you will find SEGMENTATION FAULT and you cant debug your code ahead.

So in that all case our best friend is Valgrind

Introduction:

The Valgrind tool suite provides a number of debugging and profiling tools that help you make your programs faster
and more correct. The most popular of these tools is called Memcheck. It can detect many memory-related errors
that are common in C and C++ programs and that can lead to crashes and unpredictable behaviour.
