<pre>I think the example says it all:
$ cat a.c
#include <stdio.h>
int main()
{
int i;
printf("enter a number: ");
scanf("%d", &i);
printf("got %d\n", i);
return 0;
}
$ gcc a.c
$ lldb a.out -o run
(lldb) target create "a.out"
Current executable set to 'a.out' (x86_64).
(lldb) run
enter a number: 47
42
