CPU ID using C ++ windows

I want to get the CPU ID of my computer (windows) using C ++.

I used this code to get it.

It displays information like this:

For InfoType 0
CPUInfo[0] = 0x5
CPUInfo[1] = 0x756e6547
CPUInfo[2] = 0x6c65746e
CPUInfo[3] = 0x49656e69

For InfoType 1
CPUInfo[0] = 0xf31
CPUInfo[1] = 0x20800
CPUInfo[2] = 0x41d
CPUInfo[3] = 0xbfebfbff

For InfoType 2
CPUInfo[0] = 0x605b5001
CPUInfo[1] = 0x0
CPUInfo[2] = 0x0
CPUInfo[3] = 0x7c7040

For InfoType 3
CPUInfo[0] = 0x0
CPUInfo[1] = 0x0
CPUInfo[2] = 0x0
CPUInfo[3] = 0x0

For InfoType 4
CPUInfo[0] = 0x0
CPUInfo[1] = 0x0
CPUInfo[2] = 0x0
CPUInfo[3] = 0x0

For InfoType 5
CPUInfo[0] = 0x40
CPUInfo[1] = 0x40
CPUInfo[2] = 0x0
CPUInfo[3] = 0x0

For InfoType 80000000
CPUInfo[0] = 0x80000008
CPUInfo[1] = 0x0
CPUInfo[2] = 0x0
CPUInfo[3] = 0x0

For InfoType 80000001
CPUInfo[0] = 0x0
CPUInfo[1] = 0x0
CPUInfo[2] = 0x0
CPUInfo[3] = 0x0

For InfoType 80000002
CPUInfo[0] = 0x20202020
CPUInfo[1] = 0x20202020
CPUInfo[2] = 0x20202020
CPUInfo[3] = 0x20202020

For InfoType 80000003
CPUInfo[0] = 0x47202020
CPUInfo[1] = 0x69756e65
CPUInfo[2] = 0x4920656e
CPUInfo[3] = 0x6c65746e

For InfoType 80000004
CPUInfo[0] = 0x20295228
CPUInfo[1] = 0x20555043
CPUInfo[2] = 0x30382e32
CPUInfo[3] = 0x7a4847

For InfoType 80000005
CPUInfo[0] = 0x0
CPUInfo[1] = 0x0
CPUInfo[2] = 0x0
CPUInfo[3] = 0x0

For InfoType 80000006
CPUInfo[0] = 0x0
CPUInfo[1] = 0x0
CPUInfo[2] = 0x4008040
CPUInfo[3] = 0x0

For InfoType 80000007
CPUInfo[0] = 0x0
CPUInfo[1] = 0x0
CPUInfo[2] = 0x0
CPUInfo[3] = 0x0

For InfoType 80000008
CPUInfo[0] = 0x2028
CPUInfo[1] = 0x0
CPUInfo[2] = 0x0
CPUInfo[3] = 0x0

I could not understand among the information, which is the unique identifier of the CPU of my computer.

Can anyone help me with this.

You mean "serial number", "who made the processor" or "a string that identifies the make and model of the processor."

Serial number:

If you do not have a Pentium III, you do not have a “unique identifier” associated with your processor.

Intel ( ) P3. - .

, , :

mov eax, 3
cpuid

eax, edx ecx

__cpuid, "3" . , P3.

( )

int regs[4] = {0};
char vendor[13];
__cpuid(regs, 0);              // mov eax,0; cpuid
memcpy(vendor, &regs[1], 4);   // copy EBX
memcpy(vendor+4, &regs[3], 4); // copy EDX
memcpy(vendor+8, &regs[2], 4); // copy ECX
vendor[12] = '\0';
print("My CPU is a %s\n", vendor);

"GenuineIntel".

Check here . You need to use __cpuid. Then you should extract the information based on the table.
