Opening files - Giving options?

Can anyone help please. I have made a prog that just displays text in the black dos window. Like the "Hello World" does.

However I want to add some options to open files, e.g .txt or .htm files etc.

I know how to open another .exe from within my prog, but that's not what Im after what I really need is some sort of "options screen" to open files.

I am using Dev C++

Thanx.
Gaz.

That's not real clear. Do you want to view the file when the user gives input or presses a key or do u want to run a file using another app?

I want to be able to view the file when the user gives input or presses a key e.g

press 1 for readme.txt
press 2 for Webpage.htm
press 3 to extract winzip.exe

Is it also possible to open directories?
e.g
press 4 to go to Pictures dir (D:\Pictures)

ok a little psedocode to get you going...

#include <all relevent libraries>
using namespace std;

int main()
{
int choice=1;
do
{
cout<<" A menu etc."
cout<<"enter choice"
cin>>choice;
switch(choice)
{
case 1: //do whatever
break;
case 2: // do whatever
break;
case 3: // do whatever
break;
case 4: system("dir pathname /p");
break;
case 5: cout<<"sure you want to quit?"
cin>> a char
if(tolower(thatchar)=='y') choice=0;
}
}
while(choice);
return 0;
}
