如何用C程序实现孟加拉语转C关键字及扩展array等关键字支持

1. 扩展单字词关键字映射 #

先为需要新增的C关键字补充对应的孟加拉语翻译，将它们添加到现有的关键字数组中，必须保持两个数组的元素顺序完全一致：

示例对应关系：

• array → অ্যারে
• for → জন্য
• switch → সুইচ
• case → কেস

修改后的关键字数组如下：

const char *bengali_keywords[] = {"প্রিন্ট", "যদি", "অন্যথায়", "চলাও", "ফাংশন", "অ্যারে", "জন্য", "সুইচ", "কেস"};
const char *english_keywords[] = {"print", "if", "else", "run", "function", "array", "for", "switch", "case"};

2. 处理多字词关键字（如do-while） #

多字词关键字（比如do-while对应的孟加拉语假设为কর যতক্ষণ）无法通过单个token匹配实现，需要调整代码逻辑识别连续的token组合：

修改后的完整代码 #

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

// 定义多词关键字结构体，存储短语、对应C关键字和单词数量
typedef struct {
    const char *bengali_phrase;
    const char *english_keyword;
    int word_count;
} MultiWordKeyword;

void translate_bengali_code(const char *bengali_code, char *translated_code) {
    // 单字词关键字映射
    const char *bengali_keywords[] = {"প্রিন্ট", "যদি", "অন্যথায়", "চলাও", "ফাংশন", "অ্যারে", "জন্য", "সুইচ", "কেস"};
    const char *english_keywords[] = {"print", "if", "else", "run", "function", "array", "for", "switch", "case"};
    int num_single_keywords = sizeof(bengali_keywords) / sizeof(bengali_keywords[0]);

    // 多字词关键字映射（可根据实际孟加拉语表达调整）
    MultiWordKeyword multi_keywords[] = {
        {"কর যতক্ষণ", "do-while", 2},
        {"সুইচ-কেস", "switch-case", 1}
    };
    int num_multi_keywords = sizeof(multi_keywords) / sizeof(multi_keywords[0]);

    char buffer[1024] = "";
    char *tokens[100]; // 存储拆分后的所有token
    char code_copy[1024];
    int token_count = 0;

    strcpy(code_copy, bengali_code);
    
    // 先拆分所有token并存储
    char *token = strtok(code_copy, " ");
    while (token != NULL) {
        tokens[token_count++] = token;
        token = strtok(NULL, " ");
    }

    // 遍历token，优先处理多字词，再处理单字词
    int i = 0;
    while (i < token_count) {
        int found_multi = 0;
        // 检查多字词关键字
        for (int m = 0; m < num_multi_keywords; m++) {
            if (i + multi_keywords[m].word_count <= token_count) {
                // 拼接连续token，匹配多词短语
                char temp_phrase[100] = "";
                for (int w = 0; w < multi_keywords[m].word_count; w++) {
                    strcat(temp_phrase, tokens[i + w]);
                    if (w != multi_keywords[m].word_count - 1) {
                        strcat(temp_phrase, " ");
                    }
                }
                if (strcmp(temp_phrase, multi_keywords[m].bengali_phrase) == 0) {
                    strcat(buffer, multi_keywords[m].english_keyword);
                    strcat(buffer, " ");
                    i += multi_keywords[m].word_count; // 跳过已匹配的token
                    found_multi = 1;
                    break;
                }
            }
        }
        if (found_multi) {
            continue;
        }

        // 检查单字词关键字
        int found_single = 0;
        for (int s = 0; s < num_single_keywords; s++) {
            if (strcmp(tokens[i], bengali_keywords[s]) == 0) {
                strcat(buffer, english_keywords[s]);
                found_single = 1;
                break;
            }
        }
        if (!found_single) {
            strcat(buffer, tokens[i]);
        }
        strcat(buffer, " ");
        i++;
    }

    // 移除末尾多余的空格
    buffer[strcspn(buffer, " ")] = 0;
    strcpy(translated_code, buffer);
}

int main() {
    const char bengali_code[] = "প্রিন্ট 'Hello, World!' যদি অন্যথায় জন্য অ্যারে কর যতক্ষণ সুইচ কেস";
    char translated_code[1024];

    translate_bengali_code(bengali_code, translated_code);
    
    printf("Original Bengali Code: %s\n", bengali_code);
    printf("Translated English Code: %s\n", translated_code);

    return 0;
}

3. 自定义调整说明 #

• 如果do-while或其他多词关键字对应的孟加拉语表达不同，直接修改multi_keywords数组中的bengali_phrase内容即可
• 新增多词关键字时，只需在multi_keywords中添加新条目，指定孟加拉语短语、对应C关键字和短语包含的单词数量
