hi,
I need to merge some mp3 files in linux,
now I can write this command in linux command prompt :
CODE
cat a.mp3 b.mp3>>c.mp3

and I get c.mp3 file that composed of a.mp3+b.mp3
does anyone knows how to do it in c/c++ (I have many mp3 files to merge)

I tried some options like this:
CODE
#include <iostream>
#include <string>
#include <cstdlib>

using namespace std;

int main ()
{
    
    "cat a.mp3 b.mp3>>c.mp3";
            
    return 0;
}

but it failed to do it.

thanks in advance

Not exactly how I would do it... but this should fix your error biggrin.gif
cpp
#include <iostream>
#include <string>
#include <cstdlib>

using namespace std;

int main () {
	
	system("cat a.mp3 b.mp3>>c.mp3");
			
	return 0;
}

Gah don't do it in a C++ program, do it in a shell script.

"system( )" does that for Linux?! I thought it would only work with Windows.

Nope. system() is a standard C function. The results of running it depend on the OS though.
