Need help with threads in C++


Hi I need an example of how threads are coded and implemented in Dev-C++, any help would be greatly appreciated. :)
Try this and see if it works..... But the problem is some libraries does not support  

(#include "XYLock.h")



```
#include <stdio.h>
#include  <iostream>
#include "XYLock.h"

XYCriticalSection myCriticalSection;

void ThreadProc(void *dummy)
{
    while(true)
    {
        try
        {
            XYLock myLock(&myCriticalSection);
            printf("Thread '%X' has the lock\n",::GetCurrentThreadId());
            throw "a test";
        }
        catch(char* p)
        {
            printf("Caught: %s\n",p);
        }
        ::Sleep(1000);
    }
}

void main()
{
    for(int i=0;i<100;i++)
    {
        if(_beginthread(ThreadProc,0,NULL)1)
        {
            printf("Failed to create a thread\n");
            return;
        }
    }

    while(true)
    {
        try
        {
            XYLock myLock(&myCriticalSection);
            printf("The main thread '%X' has the lock\n",::GetCurrentThreadId());
            throw "a test from the main thread";
        }
        catch(char* p) 
        {
            printf("Caught: %s\n",p); 
        } 
        ::Sleep(1000); 
    } 
}
```

error: c++11 is required and is missing or failed to compile.

i can’t help with most of that, but for c++11, see:

<https://gcc.gnu.org/projects/cxx-status.html#cxx11>

you probably must explicitly pass argument “-std=c++11” (or in some cases, perhaps “-std=gnu++11”).

I don’t have any personal experience with .NET code generation tools, but I can refer you to a very good website that provides information and resources on code generation. Checkout:


 http://www.codegeneration.net/


On this site, you will find interviews, technical articles, book references, and product/tool lists for specific platform. There are some very good resources on OMG Model-Driven Architecture (MDA), Intentional Programming, and other generative programming techniques.


Checkout the .NET page (http://www.codegeneration.net/tiki-index.php?page=NET) for specifics on .NET tools. There is also a complete list of code generators in the left-hand navigation bar (under “Generators”).


Good luck!

greets,

voidisalive Two main programming languages are the best when used in robotics: C++ and Python, often used together as each one has pros and cons. C++ is used in control loops, image processing and to interface low-level hardware.Thank You not [full disclosure] a linux person per se.

something similar to the following should work:

https://www.unix.com/shell-programming-and-scripting/68166-converting-integer-string.html

start simple with just enough code to test the concept.

see if it works and modify/correct as necessary.

then if it still does not work, then post your documented code accordingly along an explanation of what is or is not happening as you expect or desire. hi ! dusty\_nv.

i deeply thank you for always providing the best suggestion and the best code.

if you are in trouble again, please help.

thank you. We need the whole code to answer to your question. [submit your assignment](https://www.assignmentexpert.com/submit) to our control panel and our experts will help you. Unicode can be a problem, and Perl has its own quirks. Essentially, Perl creates a firewall that surrounds all Unicode I / O capabilities. You must tell Perl if the I / O path is encoded. If so, the DECODE rule for any input and / or ENCODE for any output.


Decoding converts the data from {encoding} to Perl's internal representation, which is probably a combination of bytes and code points.


The coding is just the opposite.


Thus, it is actually possible to "decode into" and "encode" up to two different encodings. You just need to say what it is. Encoding / decoding is usually done with the file I / O layer, but you can use the encoding module (distribution part) to manually convert between encodings.


 [perldocs in Unicode](https://translate.googleusercontent.com/translate_c?depth=1&pto=aue&rurl=translate.google.com&sl=ru&sp=nmt4&tl=en&u=) does not read light.

Here's an example that can help visualize it (there are many other ways).



```
use strict;
use warnings;
use Encode;


# This is an internalized string with these UTF-8 codepoints
# 
my $internal_string_1 = "\x{C7}\x{69}\x{64}\x{65}\x{6D}\x{5F}\x{15E}\x{65}\x{6E}\x{65}\x{72}\x{20}\x{48}\x{FC}\x{73}\x{6E}\x{FC}\x{20}\x{54}\x{61}\x{11F}\x{6C}\x{69}\x{70}";


# Open a temp file for writing as UTF-8.
# Output to this file will be automatically encoded from Perl internal to UTF-8 octets.
# Write the internal string.
# Check the file with a UTF-8 editor.
# 
open (my $out, '>:utf8', 'temp.txt') or die "can't open temp.txt for writing $!";
print $out $internal_string_1;
close $out;


# Open the temp file for readin as UTF-8.
# All input from this file will be automatically decoded as UTF-8 octets to Perl internal.
# Read/decode to a different internal string.
# 
open (my $in, '<:utf8', 'temp.txt') or die "can't open temp.txt for reading $!";
$/ = undef;
my $internal_string_2 = <$in>;
close $in;


# Change the binmode of STDOUT to UTF-8.
# Output to STDOUT will now be automatically encoded from Perl internal to UTF-8 octets.
# Capture STDOUT to a file then check with a UTF-8 editor.
# 
binmode STDOUT, ':utf8';
print $internal_string_2, "\n\n";


# Use encode() to convert an internal string to UTF-8 octets
# Format the UTF-8 octets to hex values
# Print to STDOUT
# 
my $octets = encode ("utf8", $internal_string_2);
print "Encoded (out) string -> UTF-8 (octets):\n";
print " length = ".length($octets)."\n";
print " octets = $octets\n";
print " HEX val = ";
for (split //, $octets) {
    printf ("0x%X ", ord($_));
}
print "\n\n";


# Use decode() to convert external UTF-8 octets to an internal string.
# Format the internal string to codepoints (hex values).
# Print to STDOUT.
# 
my $internal_string_3 = decode ("utf8", $octets);
print "Decoded (in) string <- UTF-8 (octets):\n";
print " length = ".length($internal_string_3)."\n";
print " string = $internal\_string\_3\n";
print " code points = ";
for (split //, $internal_string_3) {
    printf ("\\x{%X} ", ord($_));
}

        

        
        
        
 (adsbygoogle = window.adsbygoogle || []).push({});
