[英]C++ wrong letter for output
Hello I have new question about Caesar cipher for example 您好,例如,我对Caesar密码有新问题
Key: 3 键:3
Plain: ABCÇDEFGĞHIİJKLMNOÖPRSŞTUÜVYZ 平原:ABCÇDEFGĞHIİJKLMNOÖPRSŞTUÜVYZ
Cipher: DEFGĞHIİJKLMNOÖPRSŞTUÜVYZABCD 密码:DEFGĞHIİJKLMNOÖPRSŞTUÜVYZABCD
These are Turkish letters " ç ,ı ,ğ, ö , ş , ü , Ç, İ , Ğ, Ö, Ş, Ü " 这些是土耳其语字母“ç,ı,ğ,ö,ş,ü,Ç,İ,Ğ,Ö,Ş,Ü”
I need to make encryption and decryption and program shouldnt have case sensitive. 我需要进行加密和解密,并且程序不应该区分大小写。 It should be like s=S, ç=Ç
应该像s = S,ç=Ç
You can see my program below ,but I have some problems 您可以在下面看到我的程序,但是我有一些问题
1) Text(Plain) and key should entered by user but I couldnt do it. 1)文本(普通)和密钥应该由用户输入,但我做不到。
2) char text[] = "DEF"; 2)char text [] =“ DEF”; this input should give (for decrypt) "CÇD" but it gives "CÃD"
此输入应给出(用于解密)“CÇD”,但给出“CÃD”
normally it should give "Ç" instead of "Ã" 通常应使用“Ç”代替“Ô
I need help :( 我需要帮助 :(

This issue is that your program is using a different encoding than the one the console expects. 此问题是您的程序使用的编码与控制台期望的编码不同。 Windows is configured this way by default;
Windows默认情况下是用这种方式配置的; programs use encodings like cp1252 or cp1254 and the console expects something else like cp437.
程序使用诸如cp1252或cp1254之类的编码,并且控制台期望使用诸如cp437之类的其他内容。
Here's an article from a Microsoft developer that explains why this is. 这是Microsoft开发人员的文章,解释了为什么会这样。
There's already a lot of information online covering the numerous ways you can fix the encoding mismatch. 在线信息已经很多,涵盖了许多解决编码不匹配的方法。
