1. 

$ echo disass main | gdb --silent test200
Reading symbols from test200...done.
(gdb) Dump of assembler code for function main:
0x080483eb <+0>: push %ebp
0x080483ec <+1>: mov %esp,%ebp
0x080483ee <+3>: mov $0x0,%eax
0x080483f3 <+8>: pop %ebp
0x080483f4 <+9>: ret
End of assembler dump.
(gdb) quit
