I'm a new bee in arm assembly language.I objdump a simple program, and the following is the assembly code of main function:
00010438 <main>:
10438: e92d4800 push {fp, lr}
1043c: e28db004 add fp, sp, #4
10440: e24dd010 sub sp, sp, #16
10444: e59f3068 ldr r3, [pc, #104] ; 104b4 <main+0x7c> <--(QUESTION:0x10444+104≠0x104b4, why?)
10448: e50b300c str r3, [fp, #-12]
1044c: e59f3064 ldr r3, [pc, #100] ; 104b8 <main+0x80>

104bc: 00010548 .word 0x00010548
104c0: 00010540 .word 0x00010540
My question is on line 5 of the code above.Thanks.
