Hi,
I posted this message on gcc/bug forum earlier. I repost the same contents
here. I need experts to shed light on C/C++ data type size inconsistencies
when running 64-bit and 32-bit ELF executables compiled by GNU/GCC g++/gcc
Following are results of C/C++ data type size from code " cout << "data
type" << sizeof(data type) << endl " :
| 32-bit | 64-bit
-------------------------------
int | 4 | 4
-------------------------------
long int | 4 | 8
-------------------------------
signed long int | 4 | 4
-------------------------------
ulong | 4 | 8 (sys/types.h)
-------------------------------
long double | 12 | 16
Thank in advance,
Tom
