how to run a program in terminal using c++/python program and then execute statements in that program

Question

I want to create a GUI for GDB debugger, so I need a way to run GDB debugger in terminal and execute commands in that and also get output from that on user triggered events on my screen in ubuntu. how can I do that for such a program?

it tried

int main(){
    system("gnome-terminal 'gdb  test'");
    system("break main");
    return 0;
}

but it executes the command on the terminal not on the gdb program

System will not feed gdb input. Pass a gdb script to gdb instead. — Jean-François Fabre, Jul 29 '16 at 16:59

Each of the system() calls opens a separate shell. So these are independent of each other.

If you want to continuously communicate with a child process, rather use popen() please.

@kar09 Using I/O (file descriptors). Check the `popen()` examples around on the interwebz. (and read the link I've provided) – πάντα ῥεῖ Jul 29 '16 at 17:17
