Eclipse CDT: Problem in running simple C program

Hi all,

I just installed CDT tool for C programming under Eclipse, but when compiling the first simple program:

Code:

---

#include<stdio.h>

int main(){

  char name[30];
  printf("Enter your name\n"); 
  scanf("%s", &name);
  printf("Your name is %s", name);
  return 0;

}

---

The console did not show the first printf, it waits for input from the user. like this:

console:

Mark
Enter your name
Your name is Mark

I compiled this code under cygwin with gcc compiler and it works fine. Can anybody tell me if this is becuase a wrong installation of the CDT tool?

Remove the '&' operator from the second argument in scanf

maybe need to fflush(stdout) before scanf?

That solved the issue. But, using gcc ver. 3.4.4 it compiles fine without fflush(). Can you give any reason of why and what is the cause of this?

Buffered output is only flushed automatically at a "\n".

If you want to guarantee that you see output for anything which doesn't end with a newline, say a prompt of some sort, then you must follow it with a flush of the output stream.

The fact that some systems don't need it is just one of the many subtle system dependencies which keep everyone on their toes.

Why including \n in : printf("Enter your name: \n") did not flush the output?

That just seems wrong to me - have you checked the Eclipse bug pages?
