I use MinGW64 to compile c++ programs. But since I upgraded to Windows 10, I found my c program output Chinese will be garbled code.
I follow the online method, adding a code in the program header: SetConsoleOutputCP(65001);, then it fixes. but I think it's so troublesome to do this for each c++ program. What should I do?
I think this is my system's problem, the same code in Windows 7 is not a problem, I just want to find a more convenient solution instead of adding the same code to every file
There's the code:
#include <iostream>
#include <windows.h>
using namespace std;
int main()
{
SetConsoleOutputCP(65001);
cout << "文本" ; //Output will be garbled code if there's no line above
return 0;
}
The console in most operating systems only expects ASCII character input. In order to show some other char set you have to specify that in your code. The SetConsoleOutputCP command sets the "code page" windows should read from. By the way not all versions of windows have the same code for this command.
Please refer to the documentation found here.
The documentation suggests using EnumSystemCodePages to make sure the code for that language exists on that system.
P.S.
Your English is very good :)
EDIT
I tested your code on my computer with Visual Studio 2019 and got the following
Warning C4566 character represented by universal-character-name '\u6587' cannot be represented in the current code page (1255)
even with the SetConsoleOutputCP command you added. I assume you need to have chines installed for this to work. The problem is that I don't have the relevant code page for the windows console to look in for the char set. see this answer and this answer.
I am debugging a program that I have built. The program compiles and runs without error.
When using the debugger gcc4.9.3 (rtools_34) I get a message:
'No source available for "std::ostream::operator<<()"'
When stepping over any lines that contain std::cout << "Text" << std::endl;
This causes the debugging to crash. However if I set a breakpoint past the rogue code I can skip it without problem.
The code includes: iostream, ostream and string.
This code has also been debugged with other compilers without this issue. It is a new import into Eclipse for a newer compiler so I am assuming that I have set things up wrong.
The problem appears to be with std::endl as using '\n' instead works.
Any hints on interpretation of the error message or how to resolve the problem greatly appreciated.
Have you remembered to
#include <string>?
Sorry if that was obvious and has been checked, it just wasn't clear that that was definitely the case from your question!
that's my first use to code block but it hasn't gone fine ,, i face a really weird problem
i cant even describe it so i will just tell you what's happened.
the problem is that the ide dont compile my project even if the code were correct
its just open a new tab that called "iostream" and the console window appears but empty
why do that happens ?
look to the code which the ide face a problem while compiling it ,, simplest code ever
#include <iostream>
using namespace std;
int main()
{
cout << "Hello world!" << endl;
return 0;
}
and this is the compiling results...
thats all..
will codeblocks stop annoying me ?
This line is not valid syntax
usingnamespace std;
Those are two separate keywords
using namespace std;
And since you are just starting C++, Lesson 1: Don't do that.
This is my first post here, so sorry if it's a little bit bad :I but I have a problem. When I tried to make a Hello World C++ project in Eclipse (first time trying c++) I tried to build the project and run it, but it said that there are errors. Here is the code:
#include <iostream>
using namespace std;
int main() {
cout << "!!!Hello World!!!" << endl; // prints !!!Hello World!!!
return 0;
}
And also here is a screenshot of the errors:
I tried looking but couldn't find a solution, so sorry if I look stupid for being a total noob :\ All and any help is appreciated. :) Thanks!
The code looks good to me. I think you didn't setup C++ in Eclipse correctly.
Follow the step-by-step setup here. You should be able to work it out after correct setup.
I am using C++ on Netbeans 7.1 on Ubuntu 11.04. For some reason, the following code results in the error message "Unable to resolve identifier cout".
#include <iostream>
using namespace std;
int main()
{
std::cout << "Hello,world!\n";
return 0;
}
Any help resolving this problem would be greatly appreciated.
The solution for your problem is at least strange ;)
Once iostream header is added, one has to reparse code. Click right on a project, go to code assistance and click to reparse project. Worked for me.
I was using netbeans for mac.
check whether iostream is really getting included;
i have tried your code on my machine using eclipse cdt it worked fine.so, please check the
includes.
What sort of file is this in? Is it a .h file, or .hpp file? I had this same issue. Netbeans can be ridiculous sometimes with C++. For me, I changed #include <iostream> to #include<iostream.h>
This may seem too simple, but...
In my NetBeans installation, when I go to create a new project, specify C/C++, it brings up a dialog box prompting for "Project Name:", location, folder, makefile name, and then...
a check box for "Create Main File", an edit box with "main" filled in, and to the right of that is a drop down list that reads "C". If you hit Finish, this will create "main.c" (C, but NOT a C++ file). Instead, in the drop down list, select "C++". Then the IDE creates main.cpp, which will be compiled with g++ and will find those includes and functions.
There is a difference between std::cout and cout. You don't currently have std::cout defined in your file. std::cout is a c standard out. In C++ we only need cout to work with iostream.
If you must use a standard c out then do the following:
Add this to the top under iostream
#include <iostream> //Input output stream in C++
#include <cstdlib> //Stands for c standard library
using namespace std;
Your code will now work because:
This change defines std::cout and std::cin among other things. (standard in, standard out respectively.)
However, I'd recommend this alternative if you don't need standard in outs:
Replace std::cout with cout, because cout is defined in iostream in C++. Your program would have worked without the std:: portion of your cin cout commands because you originally included iostream.
Try taking out the using namespace std; - it's generally considered bad form anyway :-)
I'm not sure that will fix the problem but most people either use the namespace or fully qualify things like std::cout. I've never seen code that does both.
The other thing to check is that the iostream header actually is being bought in. In other words, are there any errors on that line. A lot of problems (at least in the Windows world, so it may not necessarily apply to you) seem to be due to faulty path setup in NetBeans.
Hey look at your Output Debug. You may see "no permission". After I changed the file permission of "/YourProjekt/dist/Debug/GNU-Linux/file" to runable and everyone can read and write the error disappeared. (BTW: I had the bug because I was on a NTFS System with my Projekt, it have to be ext partition)
Hope I can help you with that.
Try taking out the std:: next to cout
