I know this is basic stuff but i really don't know how to solve it.
Look at this code:
#include <stdio.h>
int main()
{
int number;
printf( "Please enter a number: " );
scanf( "%d", &number );
printf( "You entered %d", number );
return 0;
}
If i run it like an executable it does what's expected:
Please enter a number: 2
You entered 2
The problem is, if i run it in eclipse's console, "Please enter a
number: " doesn't appear. the program just waits for my input like it
has ignored the printf. The i put 2, for example and what appears is:
2
Please enter a number: You entered 2
What i want is the console to do the same as the executable. Can it be done?
Thanks

#include <stdio.h>
#include <stdlib.h>
int main(void)
{
int number;
printf( "Please enter a number: " );
fflush(stdout);
scanf( "%d", &number );
printf( "\nYou entered %d", number );
fflush(stdout);
return EXIT_SUCCESS;
}
you should read up some tutorials on c... try search google :P
