How to take console input for C/C++ program in Eclipse CDT

Question

I have eclipse June CDT with gcc4 and gdb via cygwin on Windows7. I can't seem to taken input from the console. I searched around and it might be related to EOF for eclipse which might be resolved by unchecking "Connect process input & output to a terminal" in the Run/Debug configuration. But I can't seem to uncheck it.

Can anyone suggest best way to fix this issue.

#include <stdio.h>
#include <stdlib.h>

void menu();
int main(void) {


    menu();
    return 0;
}


void menu()
{
    int i=0;
     printf(" \n1. Push to Queue");
         printf(" \n2. Pop from Queue");
         printf(" \n3. Display Data of Queue");
         printf(" \n4. Exit\n");
         while(1)
         {
              printf(" \nChoose Option: ");
              scanf("%d",&i);
              switch(i)
              {
                    case 1:
                    {
                         int value;
                         printf("\nEnter a valueber to push into Queue: ");
                         scanf("%d",&value);
                        // push(value);
                        // display();
                         break;
                    }
                    case 2:
                    {
                        // delQueue();
                        // display();
                         break;
                    }
                    case 3:
                    {
                        // display();
                         break;
                    }
                    case 4:
                    {
                         exit(0);
                    }
                    default:
                    {
                         printf("\nwrong choice for operation");
                    }
              }
         }

}

Answer 1

Found a pair of relevant related SO questions:

• Eclipse CDT Console output not showing up in debug with path and not showing up in run without path
• C++ program written in Eclipse using Windows and MinGW cannot display output to console view

Long story short, they are saying that cygwin is treated "differently" as a buffer compared with other OS's, and because of this the console is not as "interactive" as it (probably) should be. Some solutions recommend an explicit flush of the buffer, while others offer configuration options.

You need to configure the command line arguments for Eclipse: Under Run configurations>Arguments

Also consider using Ant as a build script. Works better in the long run.
