How To Enable C99 Mode In Dev C++

How To Enable C99 Mode In Dev C Windows 7

Dev-C++ is a free IDE for Windows that uses either MinGW or TDM-GCC as underlying compiler.
Originally released by Bloodshed Software, but abandoned in 2006, it has recently been forked by Orwell, including a choice of more recent compilers. It can be downloaded from:
http://orwelldevcpp.blogspot.com

Installation

Run the downloaded executable file, and follow its instructions. The default options are fine.

Support for C++11

By default, support for the most recent version of C++ is not enabled. It shall be explicitly enabled by going to:
Tools -> Compiler Options
Here, select the 'Settings' tab, and within it, the 'Code Generation' tab. There, in 'Language standard (-std)' select 'ISO C++ 11':
Ok that. You are now ready to compile C++11!

Compiling console applications

To compile and run simple console applications such as those used as examples in these tutorials it is enough with opening the file with Dev-C++ and hit F11.
As an example, try:
File -> New -> Source File (or Ctrl+N)
There, write the following:
Then:
File -> Save As... (or Ctrl+Alt+S)
And save it with some file name with a .cpp extension, such as example.cpp.
Now, hitting F11 should compile and run the program.
If you get an error on the type of x, the compiler does not understand the new meaning given to auto since C++11. Please, make sure you downloaded the latest version as linked above, and that you enabled the compiler options to compile C++11 as described above.

C99 is the 1999 standard of the C programming language. C is a simple, low level language, that is best suited for systems programming. This article will present a number of C99's features. Some of these features have yet to appear in C, and therefore might not be familiar to some C programmers. Well, the answer to your problem (but not to your question) is to change your IDE. Dev-C is far too old to support C11. The MinGW GCC version that ships with Dev-C is version 3.4.2, which is really old. Decent support for C11 starts roughly from 4.6.0, but since it is still experimental, the newer the better. Jan 04, 2016 These are different standards of C. By different standards I mean. New features adopted from other languages. Old features that are improved. Enhancement on security. Standardizing newly launched APIs Let me give you examples. Prior to C99 co.

When compiling my program i got this error:
Error: 'for' loop initial declaration used outside c99 mode
What is it and how can i solve it?

It's an error message about some code that you failed to show us. In
general, you can't expect us to know what the problem is unless you
show us the actual code as well as the error message.
In this case, you've lucked out. You probably have something like this:
...
for (int i = 0; i < N; i ++) {
...
}
...
which declares the loop variable as part of the for loop itself. This
feature was added to the language with the C99 standard; it's not
supported in C90.
You can either use C99 mode (but beware: gcc doesn't fully support
C99; see <http://gcc.gnu.org/c99status.html>), or you can re-write
the code to be compatible with C90:
...
int i;
...
for (i = 0; i < N; i ++) {
...
}
...
which is legal C99 as well.
