C 语言：按姓名升序排序自定义数据结构的实现

以下是使用 C 语言实现对给定数据结构按照 `name` 升序排序的示例代码： ```c #include <stdio.h> #include <string.h> typedef struct { int iindex; char strname[32]; char strphone[9]; } datastruct_t; // 比较函数用于 qsort int compare(const void *a, const void *b) { datastruct_t *dataA = (datastruct_t *)a; datastruct_t *dataB = (datastruct_t *)b; return strcmp(dataA->strname, dataB->strname); } int main() { datastruct_t data[] = { {1,"david","555-2685"}, {2,"cuppone","555-0039"}, {3,"autogrill","555-1238"}, {4,"ciakki","555-6658"}, {5,"elisa","555-9275"}, {6,"anna","555-2233"}, {7,"tenerone","555-1111"}, {8,"ufficio","555-9801"}, {9,"bruno","555-2983"}, {10,"laura","555-6697"}, {11,"antonio","555-1234"}, {12,"anna","555-0001"}, {13,"giulio","555-3456"}, {14,"zuzzicasa","555-8810"}, {15,"jasmina","555-7910"} }; int n = sizeof(data) / sizeof(data[0]); qsort(data, n, sizeof(datastruct_t), compare); for (int i = 0; i < n; i++) { printf("%d, %s, %s\n", data[i].iindex, data[i].strname, data[i].strphone); } return 0; } ``` 在上述代码中，定义了一个比较函数 `compare` 用于 `qsort` 函数的排序依据，然后在 `main` 函数中使用 `qsort` 对数据进行排序，并打印排序后的结果。 ######[AI写代码神器 | 575点数解答 | 2024-08-28 10:55:59]
