In my C programming, I've taken to using gdb as a REPL:
[EMAIL PROTECTED]:/tmp$ vi foo.c
[EMAIL PROTECTED]:/tmp$ cat foo.c
int foo(int x) {
return x * x;
}
int main(){}
[EMAIL PROTECTED]:/tmp$ gcc foo.c
[EMAIL PROTECTED]:/tmp$ gdb -q ./a.out
Using host libthread_db library
"/lib/i686/cmov/libthread_db.so.1".
(gdb) b main
Breakpoint 1 at 0x804835e
(gdb) run
Starting program: /tmp/a.out
Failed to read a valid object file image from memory.
Breakpoint 1, 0x0804835e in main ()
(gdb) p foo(2)
$1 = 4
(gdb) p foo(10)
$2 = 100
(gdb) p foo(-1)
$3 = 1
(gdb) p foo(0)
$4 = 0
(gdb) p foo(2)+foo(4)
$5 = 20
(gdb) quit
The program is running. Exit anyway? (y or n) y
[EMAIL PROTECTED]:/tmp$
Makes most debugging tasks much easier.
