C语言实现字典功能实例

好的，下面是一个简单的 C 语言字典功能的实现示例：

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

// 定义一个结构体，表示字典中的一个词条
struct Entry {
    char word[20];
    char definition[100];
};

// 定义一个函数，用于在字典中查找给定的单词
void lookup(struct Entry dictionary[], char searchWord[]) {
    int i;
    for (i = 0; i < 10; i++) {
        if (strcmp(searchWord, dictionary[i].word) == 0) {
            printf("%s\n", dictionary[i].definition);
            return;
        }
    }
    printf("Sorry, the word is not in the dictionary.\n");
}

int main() {
    // 定义一个字典，包含 10 个词条
    struct Entry dictionary[10] = {
        {"apple", "a round fruit with red, yellow, or green skin and firm white flesh"},
        {"banana", "a long curved fruit which grows in clusters and has soft pulpy flesh and yellow skin when ripe"},
        {"cat", "a small domesticated carnivorous mammal with soft fur, a short snout, and retractable claws"},
        {"dog", "a domesticated carnivorous mammal with a barking voice and a short coat"},
        {"elephant", "a very large animal with a long nose called a trunk, used for grasping objects, and two long curved ivory tusks"},
        {"fish", "a cold-blooded aquatic vertebrate with scales and gills"},
        {"grape", "a small sweet or sour fruit with a thin skin and small seeds"},
        {"horse", "a large four-legged animal with a mane and tail"},
        {"ice cream", "a cold sweet food made from frozen milk or cream"},
        {"jacket", "an outer garment worn by both men and women, typically having sleeves and a fastening down the front"}
    };

    // 从用户输入中读取要查找的单词，然后在字典中查找
    char searchWord[20];
    printf("Please enter a word to look up: ");
    scanf("%s", searchWord);
    lookup(dictionary, searchWord);

    return 0;
}

在这个例子中，我们定义了一个结构体 `Entry`，表示字典中的一个词条，包含一个单词和一个定义。然后我们定义了一个函数 `lookup`，接受一个字典数组和一个要查找的单词，用于在字典中查找给定的单词。在 `lookup` 函数中，我们使用了 `strcmp` 函数来比较两个字符串是否相等。最后，在 `main` 函数中，我们定义了一个包含 10 个词条的字典数组 `dictionary`，并从用户输入中读取要查找的单词，然后调用 `lookup` 函数在字典中查找。
