Change the command prompt on entering a command

I need to be able to change the prompt on running an executable of a c file to get a custom prompt

E.g:

$ abc

abc>

Here the user can give the commands acceptable to the program. I saw this happen for programs like MySQL and was wondering if it is possible to do this.

You can use gnu readline for custom prompt

#include <readline/readline.h>
#include <readline/history.h>


while (1)
{
   command = readline ("$abc");
   command = readline ("abc>");
   //validate your command name
   system(command);
   add_history (command); ///add command in history
}

you can include the readline library in your program to make it have a modern command line interface.

Or you can simply build a loop get each line from input and get the tokens from that line of input to execute commands, and there printout your abc> prompt.
