Hi,
I am trying to write a customize menu program for installation process of my
software. But the menu options are not comming up properly. Also my intention
is that when the user press / selects an option a new panel should be
displayed asking param for input and then display the parms (side-by-side)
along with the menu option:
#include <curses.h>
#include <menu.h>
#define ARRAY_ELEMENTS 31
#define CTRLD 4
char *choices[][31] = {
{"-install|i","Install the RPM package (required)"},
{"-erase|e","Erase the RPM package (required)"},
{"-package|p","The RPM package to install/erase (required)"},
{"-from|f","Publishing location (required)"},
{"-recursive|r","Recursively searching publish area directories for
packages"},
{"-show|sh","Show available packages from publishing locations"},
{"-help|he","Print this message and exit"},
{"-host|h","Host to install the RPM package on"},
{"-stage|s","Destination stage for the RPM package"},
{"-quiet|q","Print only error messages"},
{"-verbose|v","Print extra verbose information"},
{"-n|n","Do not execute, just show the command"},
{"-checkdep|d", "Check package dependencies (Default: don't check)"},
{"-exact|ex","Use the exact package version number (E.g. 31.0-5,
32.0-15)"},
{"-force|fo","Force installation of package"},
{"-group|g","Destination user/group for installed RPM package"},
{"-nostart|no","Do not start the server after installation"},
{"-command|c","Running as a command inside another program (hidden)"},
{"-noproxy|np","Do not use a proxy in the ssh tunnel"},
{"-port|po", "Remote host forward port (Default: 7000)"},
{"-nix","Setup a tunnel to the live Equinix site"},
{"-sc5","Setup a tunnel to the live sc5 site"},
{"-den","Setup a tunnel to the live Denver site"},
{"-preinstall|pre","Sync RPM images to host, Don't install them."},
{"-localRPMS|local","Sync RPMs to hosts and install them."},
{"-localRPMSDir","Directory to copy RPMS to."},
{"-cleanupRPMS|cleanup","Remove RPM images after the install
(default)"},
{"-onpg","Install package on the playground machine."},
{"Done","Done with selection (execute)"},
{"Exit", "Exit from this menu"},
{(char *)NULL, (char *)NULL}

it is *not the best.* anything that says in 21 days is something worth running
away from, far far away.
There is a book list that was supplied when you joined, I'd recommend using the
books off of that.

No, you have to teach yourself.
Get a C compiler for your computer
and get a copy of "Teach Yourself C in 21 days"
by Peter Aitken. It's probably the best C primer out there.
