开发平台(Platform):Linux GCC
// Code:
short short_int_1;
unsigned int u_int_tmp;
short_int_1 = 0xF0F0;
u_int_tmp = short_int_1;
printf("u_int_tmp = %#010x\n", u_int_tmp);
u_int_tmp = 0;
printf("u_int_tmp = %#010x\n", u_int_tmp);
u_int_tmp = u_int_tmp | short_int_1;
printf("u_int_tmp = %#010x\n", u_int_tmp);

你有意识到这 signed short 是负数吗?

请问有办法将short以bit copy的方式assign给int吗？回楼上，我知道这个short是负数

(unsigned int)(unsigned short)signed_short_value

sign extension / zero extension

感谢LPH66的方法我会找时间搜寻firose的提示，感谢分享资讯

话说那样 signed 转 unsigned 到底是怎么定义的呢?

http://busybox.net/~landley/c99-draft.html#6.3.1.3我想应该是根据6.3.1.3#2

got it thanks
