but there's errors in old syntax if we use old tutorials
coz, there's tutorials using old syntax of C and that's not used in today's C's syntax anymore
e.g.: i have K&R book and their example is like:
#include <stdio.h>
main () { }
that's why i'm looking more for tutor that suit with the latest C's syntax, which is C17

I didn't say it has not changed. It changed, but just a little. You haven't to go back to K&R. While probably there aren't yet many tutorials on the latest standard, there are many many available good ones for recent versions of it. That could be your fishing pond.

ok, i guess i'll go for tutorials around 2015 and above
do you have any suggestions on this?

i searched more for C17 and not just C tutorials
coz, there's tutorials using old syntax of C and that's not used in today's C's syntax anymore
e.g.: i have K&R book and their example is like:
#include <stdio.h>

ok, you have any suggested references for C tutorials? e-books, web, or anything...
|
|
|
|
|
Why do you need a tutorial? Read the latest K & R.

This is a "pre-introduction" series of 5 videos, to the Handmade Hero video series. HH is an ongoing series and may/may not be valuable to you, but the prelim is a good, fast intro that explains a bunch of concepts on Windows.

I was trying to use win API
GetComputerObjectNameW as below but I am getting error. Can someone help me.
#include <iostream>
#include <atlbase.h>
#include <secext.h>
typedef enum {
NameUnknown,
NameFullyQualifiedDN,
NameSamCompatible,
NameDisplay,
NameUniqueId,
NameCanonical,
NameUserPrincipal,
NameCanonicalEx,
NameServicePrincipal,
NameDnsDomain,
NameGivenName,
NameSurname
} EXTENDED_NAME_FORMAT, *PEXTENDED_NAME_FORMAT;
int main()
{
EXTENDED_NAME_FORMAT enf = NameFullyQualifiedDN;
LPWSTR pwszComputerName;
DWORD dwLen;
dwLen = 0;
GetComputerObjectNameW(enf, NULL, &dwLen);
pwszComputerName = new WCHAR[dwLen + 1];
if(NULL == pwszComputerName)
{
return 0;
}
if(!GetComputerObjectNameW(NameSamCompatible, pwszComputerName, &dwLen))
{
delete pwszComputerName;
return 0;
}
sbstrTrustee = pwszComputerName;
wprintf(L"GetComputerObjectName: %s\n", pwszComputerName);
delete pwszComputerName;
}
Some of Error message is as below.

Why do you redefine the EXTENDED_NAME_FORMAT enumeration? 
|
|
|
|
|
I first try without defining enum after that try with enum. In both case I am getting compilation error.
|
|
|
|
|
Add these definition:
#define _WIN32_WINNT 0x0500
#define SECURITY_WIN32
Remove the redefinition of enum.
Define the sbstrTrustee variable.
// edited: also don't forget to include the Secur32.lib library.

Hi Victor,
I have modified program according to your suggestion but I am not getting expected result. I want to use NameFullyQualifiedDN enum value and get the fully qualified distinguished name (for example, CN=Jeff Smith,OU=Users,DC=Engineering,DC=Microsoft,DC=Com).
Regards,
Rajnesh

Sorry, I don't know what is wrong/correct in your test.
I've just tested your code and got the result in the form:
[my_domain_name].[my_computer_name]$
wich is in my case 100% correct.

Hi Victor,
There was configuration issue with my windows laptop, so I was facing issue. Thanks for your feedback.

Good morning,
You are including the wrong header. Remove secext.h and add:
#include <Security.h> The error message is telling you that it doesn't know the definition of SEC_ENTRY.

You are putting holes in your arrays of even and odd elements. In order to avoid that, you need to maintain two separate variables to keep track of how many even and odd items have been added so far. Try
#include <stdio.h>
#define SIZE 20
int main()
{
int items, odd_items, even_items;
int array[SIZE], odd[SIZE], even[SIZE];
printf("enter how many array elements\n");
scanf("%d",&items);
odd_items = even_items = 0;
for (int n=0; n<items; ++n)
{
printf("enter item %d:\n", n);
scanf("%d", &array[n]);
if ( (array[n] % 2) == 0)
{
even[even_items] = array[n];
++even_items;
}
else
{
odd[odd_items] = array[n];
++odd_items;
}
}
printf("array items\n");
for (int n=0; n<items; ++n)
printf("%d ", array[n]);
printf("\n");
printf("even array items\n");
for (int n=0; n<even_items; ++n)
printf("%d ", even[n]);
printf("\n");
printf("odd array items\n");
for (int n=0; n<odd_items; ++n)
printf("%d ", odd[n]);
printf("\n");
return 0;
}

5, but you should get 10 for looking at code formatted this way.

Hi,
#include<stdio.h>
int main()
{
char str[20] = "Hello";
char *const p=str;
*p='M';
printf("%s\n", str);
return 0;
}
output:
Mello
As per my knowledge when we use const then we can't change a char in t then how output is Mello instead of Hello.
