K = I + (INT) j
Union)If the Union contains data types of different lengths, this may cause problems. For example, Example 3 is a common open-source package, which can be run in ilp32 but not in lp64. The Code assumes that the unsigned short array with a length of 2 occupies the same space as long, but this is incorrect on the lp64 platform.Example 3:

1. What we call a 64-bit CPU architecture refers to the 64-bit memory expansion technology, which is an extension of the 32CPU architecture and is compatible with the original architecture. It increases the bit width between CPU and memory by increasing the operation
x86 is the standard abbreviation for Intel processor-based systems. X has nothing to do with the processor, it is a simple wildcard definition for all *86 systems, a serial number of Intel general-purpose computers, and a common set of computer instructions, since early Intel's CPU numbers are numbered as 8086,80286, Because this entire series of CPUs are instruction-compatible, so use X86 to identify the s
