用户输入后C游戏关闭

Question

我正在开发一个游戏，用户必须更改单词中的字母才能使用光标将其变为目标单词。我的代码正在运行，但是当用户输入时，光标不会移动，字母也不会更改。在“游戏状态”之前，在循环的下一次迭代之前打印符号。

#include <stdio.h>
#include <stdlib.h>
#include <stdbool.h>
#include "WordGame.h"

int main() {
    char  current_letters[] = {'b', 'e', 'l', 'l'};
    char target_letters[] = {'c', 'o', 'a', 't'};
    int position_of_cursor = 2;
    const int NUMBER_OF_LETTERS = 4;
    bool game_finished = false;
    int number_of_letter_changes = 0;
    int max = 3;

    while (number_of_letter_changes < 8) {
        display_game_state (target_letters, current_letters, NUMBER_OF_LETTERS, position_of_cursor, number_of_letter_changes);

        printf("Enter a command: ");
        char letter = get_user_char();

        if( letter == '>') {
            move_cursor_right(position_of_cursor, max);
        }
        else if ( letter == '<') {
            move_cursor_left(position_of_cursor, max);
        }

        move_cursor_right (&position_of_cursor, max);
        printf("%d", position_of_cursor);
        move_cursor_right (&position_of_cursor, max);
        printf("%d", position_of_cursor);
        number_of_letter_changes++;
    }
    return 0;
}

WordGame.c代码

#include <stdio.h>

    //1. We create the output variable with the value the user has input by keyboard

    bool finish = false;
    char dummy_char = ' ';

            finish = true;

    return res;
