[Dev-C++] Prompt

[Noorez K. <coo...@ho...>]

Just for the fun of it i made this prompt thing but it doesn't switch 
directories? Can you see how i can get it to do it?



#include <iostream>
#include <cstdlib>
using namespace std;

int system();
int main()
{
  cout << "Easy to use dos-prompt!" << endl;
  cout << "To switch dirves use this: drvswitch\n" << endl;
  char ask;

  do
  {
    cout << "Would you like to enter the system? [Y\\N]";
    cin >> ask;

    if(ask == 'y' || ask == 'Y')
    {
      system();
      system("pause");
      return 0;
    }

    else if(ask == 'n' || ask == 'N')
    {
      cout << "Bye!" << endl;
      system("pause");
      return 0;
    }

    else
    {
      cout << "What....\n" << endl;
    }

  }while(ask != 'y' || ask != 'Y' || ask != 'n' || ask != 'N');

  return 0;
}

//define the system function
int system()
{
  drvswitch:

  cout << "What drive would you like to go to?";
  char drv[8];

  cin >> drv;
  strcat(drv,":");

  system(drv);

  cout << "Now in drive " << drv << endl;
  cout << "Type in commands: " << endl;
  strcat(drv,"\\>");

  char coms[123];

  while(1)
  {
    cout << drv;
    cin.getline(coms,124);

    if(strcmp(coms,"exit")==0)
    {
      return 0;
    }

    if(strcmp(coms,"drvswitch")==0)
    {
       goto drvswitch;
    }

    system(coms);
    cout << endl;
  }//while
}

Re: [Dev-C++] Prompt

[Per W. <pw...@ia...>]

chdir() is quite good at changing directories.

When you fork another program - as you do with system("xx") - and have
it change directory, that doesn't change the directory for your program.
