将刚才的代码组合优化输出成完整的c语言代码

好的，以下是完整的 C 语言代码：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#define MAX_INPUT_LENGTH 1024
#define MAX_OUTPUT_LENGTH 2048

int main()
{
    char input[MAX_INPUT_LENGTH];
    char output[MAX_OUTPUT_LENGTH];
    char* prompt = "你: ";
    char* newline = "\n";
    char* chatgpt = "ChitGPT: ";
    char* goodbye = "ChitGPT: 再见！";
    char* command = "./ChitGPT ";

    while (1) {
        // Print prompt and read input
        printf("%s", prompt);
        fgets(input, MAX_INPUT_LENGTH, stdin);

        // Remove newline character from input
        int input_length = strlen(input);
        if (input[input_length - 1] == '\n') {
            input[input_length - 1] = '\0';
        }

        // Build command to execute
        char full_command[MAX_INPUT_LENGTH + strlen(command)];
        strcpy(full_command, command);
        strcat(full_command, input);

        // Open pipe to execute command
        FILE* pipe = popen(full_command, "r");
        if (!pipe) {
            printf("ERROR: Could not execute command\n");
            exit(EXIT_FAILURE);
        }

        // Read output from pipe
        char buffer[MAX_OUTPUT_LENGTH];
        size_t output_length = 0;
        while (fgets(buffer, MAX_OUTPUT_LENGTH, pipe) != NULL) {
            int buffer_length = strlen(buffer);
            memcpy(output + output_length, chatgpt, strlen(chatgpt));
            memcpy(output + output_length + strlen(chatgpt), buffer, buffer_length);
            output_length += strlen(chatgpt) + buffer_length;
        }

        // Close pipe and print output
        pclose(pipe);
        output[output_length] = '\0';
        printf("%s", output);

        // Check for goodbye message
        if (strstr(output, goodbye) != NULL) {
            break;
        }
    }

    return 0;
}
