I want to make an calculator in a spoken language another than English e.g. Hindi. I tried to make one using '''cout''' function but it gave me unexpected errors. Please Tell what should I do

Code Sample

cout<<name<<", "<<"कृपया ऑपरेटर दर्ज करें--> ";
cin>>op;
switch (op)
{
    case '+':
     cout<<name<<", "<<"कृपया पहला नंबर दर्ज करें--> ";
     cin>>x;
     cout<<name<<", "<<"कृपया दूसरा नंबर दर्ज करें--> ";
     cin>>y;

Result:

You need a terminal (and an appropriate font) that supports the encoding of your strings. — molbdnilo, Feb 01 '21 at 11:12
@molbdnilo Can you suggest any terminal and font. I am new to C++ so I don't know more about this things — Ashish Pawar, Feb 01 '21 at 11:17

I am not familiar with Hindi font used in console, but you need to do the following things:-

Set the correct code page using std::locale OR use unicode (for examplestd::wstring and std::wcout).
Set your console to a font that can display those characters.

I would suggest you to find the character set Hindi, like English has ASCII (classification ISO646 series).

You can find more info about wstring and wcout , here posted by a fellow user.Remember to save the code file to UTF8 (or in the correct locale) otherwise the characters will simply 'disappear' from the code.

For Display output in Hindi or any none language, we Firstly need to set UTF encoding to output encoding

#include <string>
#include <iostream>
#include <Windows.h>

int main() {
    std::string test = u8"Greek: αβγδ; German: Übergrößenträger";
    SetConsoleOutputCP(65001);
    std::cout << test;
}

What if the OP is not using Windows, or is but wants to write portable code? – underscore_d Feb 01 '21 at 11:34
@Vaibhav I am able to display the letters when I copy them and paste them in my browser but when I run my application in Command Prompt it shows question marks instead of letters – Ashish Pawar Feb 02 '21 at 10:04
maybe you can display a message by converting it message into utf-8 – Vaibhav Mahajan Feb 02 '21 at 10:32
@VaibhavMahajan Have look at [link](https://ibb.co/4p8SkDz) It is same as before after encoding UTF-8 – Ashish Pawar Feb 02 '21 at 15:47

You can use setlocale function in C++. You can include locale.h header (if you need more C specific functionality, this functionality can give possibility to play with currency, language and so on). Example code:

include <locale.h>

int main(){
    setlocale(LC_ALL,"en_US.utf8");
    
    // Your code
    
    return 0;
}

Explanation: setlocale function sets locale information to be used by the current program instead of changing whole locale. setlocale function accepts two parameters: 1. category (LC_ALL); 2. locale ("en_US.utf8"). Locales can be different. Reference: setlocale in c++ (reference) This function helped me a lot in my projects.
