Re: [Cpp-Programming] Re: what's the difference of int and long on 32bit system?

Thanks, everyone. 

So CPU architecture determines which data models (ILP32, LP64 and etc) OS uses. Compiler has options, but it just uses the one determined by CPU and OS, if it doesn't want to incur too much performance penalty. If not considering cross-platform, there's no difference using int or long when developing applications on 32bit system. Is this correct?

[Cpp-Programming] Re: what's the difference of int and long on 32bit system?

This is a misconception between the guarantee from the C++ standard
and the size of an address in a specific architecture.
note that the standard only guarantees the following: 1 ==
sizeof(char) <= sizeof(short) <= sizeof(int) <= sizeof(long) <=
sizeof(long long)
(for examples of 64-bit architectures using 32-bit width for int refer
to http://en.cppreference.com/w/cpp/language/types#Properties)

FYI size_t is the integral data type which is guaranteed to be able to
hold any address.

Best,

Re: [Cpp-Programming] what's the difference of int and long on 32bit system?

is for the arquitecture , in 32bits a int are 4 bytes, in 64bits arquitecture a int is 8 bytes.
try with cout << sizeof(int) to view the size...
good luck...

[Cpp-Programming] what's the difference of int and long on 32bit system?

In gcc/g++, int is 4 bytes, so is long. Then what's the difference between the two types? Or why defining long type as 4 bytes, if there's already 4-byte int type?

[Cpp-Programming] Survey on the impact of bugs

We are looking to survey software developers about the impact software bugs have and what practices are most effective in preventing software bugs.

To fill in the survey: http://www.surveymonkey.com/s/JBK3PD9

It will be quick. There are only 6 questions to this survey.

Pass it on.
