1、输出uint32_t
uint32_t a = 888; printf("a is %ld", a);
2、输出uint64_t
uint64_t b = 888; printf("b is %lu", b); printf("b is %lld", b);
3、输出16进制
int c =16; printf("c is 0x%08x", c);
uint32_t a = 888; printf("a is %ld", a);
uint64_t b = 888; printf("b is %lu", b); printf("b is %lld", b);
int c =16; printf("c is 0x%08x", c);
