saving output in file

[shariefbe]

Hello,
I am using system() command to save command output in txt file and i am storing in one character variable. for example

system("ls>output.txt");

but what should i do when i have to save another one command output in the same txt file continuously, for example

system("ls>output.txt");
system("lsmod>output.txt");

the output of these 2 commands should come in one txt file continously it should get over write.

So just write:

system("ls>output.txt");
system("lsmod>>output.txt");
