int main()
{
char st1[20];

Check the man pages for the following syscalls: system, exec, fork.

You should be able to do it using these.

You can also call popen() to read the stdout of the shell.

man popen pclose

Hello Blowtorch

Can you explain me about that with an example...

I used execlp("shell script name,"arguments",0) to call my shell program. But after execution, the shell program;s value is not available to my c program. But I want that value. So how can I do that. Please explain me with an example.
