Thread: Is there a problem with Dev C++?

If it doesn't it gives you errors... it doesn't care what the extension is.

The same seems to apply under Windows, as I just tested.

gcc merely throws input to other programs - the c compiler, c++ compiler, the linker, etc. I can compile C++ programs with either gcc or g++. From the man page on gcc:

file.C
C++ source code which must be preprocessed. Note that in .cxx, the last two letters must both be literally x. Likewise, .C refers to a literal capital C.

Thus, you should be able to do (I can - Win32/MinGW, gcc 3.4.2):

Code:

C:\...\Projects\cboard>cat hello.cpp
#include <iostream>

using namespace std;

int main()
{
        cout << "Hello World." << endl;
        return 0;
}

C:\...\Projects\cboard>gcc -c -o hello.o hello.cpp

C:\...\Projects\cboard>gcc -o hello.exe hello.o -lstdc++

C:\...\Projects\cboard>hello
Hello World.

C:\...\Projects\cboard>_

Of course, note the extra -lstdc++ - gcc by default won't link with the standard library - you have to do that yourself. (Of course, you can use C++ without any std stuff as well...) (Throwing the -v (verbose) switch shows that gcc invokes cc1plus.) But generally, I agree - I use gcc for C code, and g++ for C++ code.

3) why does it contain perpetual whitespace? (if you hold down rightarrow it will continue to go on into an infinity of white space instead of advancing to the next line)

3) Er... mine doesn't do that?

Dev-C++ 4.0 has "perpetual whitespace", although you can figure out where the end of the line actually is by pressing end. Dev-C++ 4.9.* can have both versions, but the default is notepad-style.

>>i dunno why u say to post the actual code that i tried??? this is
>>EXACTLY what the book says and what i tried.

Clearly the second post of code isn't - I reffer to this line:

printf("ld\n", nc;)

This won't compile as the semi-colon is inside the parentheses.
