I compiled with VC, tested a bit, the code is as follows:
#include "iostream"using namespace Std;int main (){CoutCoutcoutCoutCoutCoutreturn 0;}
The results are:
1
2
4
4
4
8
This shows that, 32-bit system, VC compiler,
Short takes up 2 bytes,
int, float, long all account for 4 bytes,
Only double takes up 8 bytes
(Easy to mistake is short and long)

Recently I encountered a well-known 32-bit SSIS package execution problem in the 64-bit SQL server environment. I have read some solutions, such as modifying the debug option (run64bitruntime = false) in ssdt or forcibly running in 32bit mode when creating a job for execution. however, I found that these methods are not suitable for large-scale automated environments. you may use these methods when testing the SSIS package, but you do not necessarily

32-bit I/O and DMA in Linux are disabled by default, but the hard disks on the computer are not that outdated! Linux is good, but if you use 16-bit I/O, your computer's performance will not be fully utilized! It doesn't matter. Come with me.
To enable 32-bit I/O and DMA, you must set it as root. To reduce the damage to the file system caused by system restart due to an error, it is best to use the single-us
I was asked this question during the interview: it is not difficult to judge the number of 1 in a 32-bit unsigned integer binary. However, it requires optimization at different layers. Now let's sort it out:1. Basic Ideas:# Include
Using namespace STD;
Int findone (unsigned int N ){
For (INT I = 0; n> 0; n> = 1)
I + = (N 1 );
Return I;
}
Int main (){
Int N;
Cin> N;
Cout
Return 0;
}
2. Optimization:The time complexity is T (m) = m, depe
Analyze memory ing process in Linux x86-32 ModePreface
The virtual memory mechanism has become an indispensable part of modern operating systems. It not only provides an independent address space for each program to ensure security, it can also improve the memory usage efficiency through swap with the disk memory. As an important part of the code on Linux, virtual memory management is very large. This is not to find out the Linux source code-level mem
