.exe in C++= 464kb

#include <iostream>
using namespace std;
int main()
{
cout<<"Hello World!\n";
system("PAUSE");
}
-------------------------------------------------
.exe in C= 15.4kb

#include <stdio.h>
int main()
{
printf("Hello World!\n");
system("PAUSE");
}
-------------------------------------------------
Why in C++ are bigger, and there is away to reduce it? THX

#include <stdio.h>
int main()
{
printf("Hello World!\n");
system("PAUSE");
}

That is also a valid C++

By the way, what is your compiler? I think this type or problem is based on compilers. Some compilers have really good code optimization, some don't. Maybe your compiler builds the exe with the C++ run-time libraries and packages, that's why you get huge exe file. Consult your compiler's documentation if that's the case.

its the Dev-C++ Ver.4.9.9.2

in the compiler options i select in the linker to strip the executable. and now the file is 260kb
before-464, but i think its still to big....

Does it make a difference if you use "using std::cout" instead of "using namespace std"?

nop, let me try Visual C++ when i finish to download it..

That's how mingw works.

For example, try:

#include <iostream>

int main() {

}

Then try:

int main() {

}

Even though you are not using anything from iostream, stuff from it still gets generated. As your projects get bigger, you'll notice less file size difference between compilers, but with small apps, you notice a big difference and even stripping is not enough to match vc++ for example. If you want to shrink a mingw/gcc-built file down more, use upx to compress it. With upx --best file.exe, you'll get hello world down to 80KB or less.

The alternative is to only include C headers and only use C functions etc., but that defeats the purpose.

There's really not much you can do except use a different compiler or get used to it.
