Little heart problem with my MSYS2 compiler
问题
你的问题似乎是在使用MSYS2编译器时出现了显示错误字符（例如心形符号）的问题。这可能是编码或终端设置的问题。要解决这个问题，你可以尝试以下几种方法：
-
字符编码问题：确保你的源代码文件以UTF-8编码保存。这可以在文本编辑器中设置。MSYS2可能对UTF-8支持较好。
-
终端设置：MSYS2的终端可能需要特定的字体或字符集设置。请检查终端的设置，确保它使用了合适的字符集，如UTF-8。
-
编译器选项：确保你在编译时没有使用任何奇怪的编译器选项，可能会影响输出的字符集。
-
库版本：MSYS2和在线编译器可能使用不同版本的标准C库，这可能会导致输出差异。确保你的环境中使用的库版本是正确的。
如果这些方法都无法解决问题，考虑使用其他编译器或集成开发环境（IDE）来编译和运行你的程序，以查看是否在特定于MSYS2的设置中出现了问题。

I am working on a homework again and my homework is a hangman game with turkish cities.
The code is not completed yet because there is a funny problem.
When I run the code with MSYS2 compiler my output suppose to look like this:
_______ //the random cities letter numbers determines how many "_" in here
Sehri tahmin et! // "Guess the city!"
Bir harf soyle //pls tell me a letter
b //user input
Tahmin ettigin harf: b // the letter u guessed
_ _ _ _ _ //?
Bir harf soyle //pls tell me a letter
u //user input
Tahmin ettigin harf: u // the letter u guessed
_ _ _ _ _ //?
Bir harf soyle //pls tell me a letter
a //user input
Tahmin ettigin harf: a // the letter u guessed
a _ _ _ _ //user input
Bir harf soyle //pls tell me a letter
But it looks like this:
_ _ _ _ _
Sehri tahmin et!// "Guess the city!"
Bir harf soyle //pls tell me a letter
b //user input
Tahmin ettigin harf: b // the letter u guessed
♥ _ _ _ _ //?
Bir harf soyle //pls tell me a letter
u //user input
Tahmin ettigin harf: u // the letter u guessed
♥ _ _ _ _ //?
Bir harf soyle //pls tell me a letter
a //user input
Tahmin ettigin harf: a // the letter u guessed
a _ _ _ _ //user input
Bir harf soyle //pls tell me a letter
There is an heart appears until I guess the first letter correctly

So my problem only appears when I use msys2 compiler but when I use an online compiler like this it works fine. How do I fix it? And why is it happening?

这个“心”字符可能是一个控制字符。ASCII控制字符执行一些控制功能，但也可以直接显示；♥ 就是其中之一，它的代码是3。
注意它显示为下划线 _ 的代替。这段代码打印 correctGuess[i].letter。所以你可以合理地确定在代码的那个位置，它具有奇怪的值3。
为什么它在那里有这个值？因为它是未初始化的；它可以有任何值。未初始化的变量通常具有值0；这可能会使你的代码看起来正常工作。
要将 correctGuess 数组全部初始化为零，你可以使用“通用”零初始化习惯用法：
struct correctGuess correctGuess[10] = {0};
或者详细初始化（如果以后要更改为非零值，并需要明确指定哪些值放在哪里）：
struct correctGuess correctGuess[10] = {
{0, 'struct correctGuess correctGuess[10] = {
{0, '\0'},
{0, '\0'},

英文:
This "heart" character is probably a control character. ASCII control characters do some control, but can also be displayed literally; ♥ is one of these, having the code 3.
Note that it's displayed instead of underscore _. The code prints correctGuess[i].letter. So you can be reasonably sure that at that place in code, it has this weird value 3.
Why does it have that value there? It's uninitialized; it can have any value. Uninitialized variables often have the value 0; this can appear as if your code works properly.
To initialize all of the correctGuess array to zeros, you can use the "generic" zero-initialization idiom:
struct correctGuess correctGuess[10] = {0};
or detailed initialization (if you want to change it to nonzeros later, and need to specify clearly which values go where):
struct correctGuess correctGuess[10] = {
{0, 'struct correctGuess correctGuess[10] = {
{0, '\0'},
{0, '\0'},
{0, '\0'},
{0, '\0'},
