    U will need to read the information on a BIOS ROM

    Different compilers have different headers for this one.

    u will first need to create a handle that would fetch the information

    I don't know much but it must be similar to fetching time from the BIOS

    hi........

    By default ANSI libraries wont provide to the capability to play with ur hardware........

    the only solution is use operating system functions(like WIN32 api functions)
    Code:
    //------------------------------------------------------------------------
    #include<windows.h>
    #include<tchar.h>
    #include<stdio.h>
    #include<string.h>
    
    #define _UNICODE
    
    void PrintSystemName()
    {
    	TCHAR compName[40];
    	int size=40;
    
    	if(GetComputerName(compName,&size)!=0)
    		_tprintf(_T("\nComputer Name : %s "),compName);
    
    }
    
    void PrintUserName()
    {
    	TCHAR uName[40];
    	int size = 40;
    
    	if(GetUserName(uName,&size) != 0)
    		_tprintf(_T("\nLogged user name : %s"),uName);
    }
    
    void PrintSystemUpTime()

    install VC++ compiler or better install windows platform SDK and open its cmd and compile the about program and run it...........

    u can also retrive processor specific info using cpuid instruction........


    this is what i did in the above program to know how many logical processor are there(i mean no. of cores)


    Code:
    __asm
    {
    mov eax,01h //01h for getting number of core present in the physical processor
    cpuid
    mov t,ebx
    }
    _tprintf(_T("\nNumber of logical processors(cores) : %d"),(t>>16)&0xff);
    
    embed assembly in C is the workaround.................

    bye.....................BORN 2 CODE
