I'm new to C, and reading some tutorials and looking over very simple codes and whatnot I copied some of them into a compiler and compiled and so forth, but I had one problem (sorry if I sound like a complete moron asking this, but I have no one to ask really); On programs asking you to submit information, they close after pressing Enter, which I automatically assumed would be use to insert that information and whatnot. Here's the code for the simplest thing if that helps:
CODE
#include <stdio.h>

int main()
{
  int this_is_a_number;

  printf( "Please enter a number: " );
  scanf( "%d", &this_is_a_number );
  printf( "You entered %d", this_is_a_number );
  getchar();
}

Thanks for any help.

Thanks.

Another question:
I'm assuming %d is used for numbers, but what would you use for text? Thanks again.

That won't work on all implementation. Better do this

CODE

printf("Hit RETURN to exit"\n");
fflush(stdout);
(void)getchar();
