C Model轉換JSON 是一種常見的數據格式轉換方式，本文將介紹如何使用C語言編寫代碼將C Model轉換為JSON字符串。

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <stdbool.h>
#include <jansson.h>
// C Model定義
typedef struct Student {
char* name;
int age;
char* gender;
bool isGraduated;
} Student;
// 將C Model轉換為JSON字符串
char* studentToJson(Student* student) {
json_t* root = json_object();
json_object_set_new(root, "name", json_string(student->name));
json_object_set_new(root, "age", json_integer(student->age));
json_object_set_new(root, "gender", json_string(student->gender));
json_object_set_new(root, "isGraduated", json_boolean(student->isGraduated));
char* jsonStr = json_dumps(root, 0);
json_decref(root);
return jsonStr;
}
int main() {
// 創建C Model對象
Student* student = (Student*)malloc(sizeof(Student));
student->name = "Tom";
student->age = 18;
student->gender = "male";
student->isGraduated = false;
// 將C Model轉換為JSON字符串
char* jsonStr = studentToJson(student);
printf("%s\n", jsonStr);
free(jsonStr);
// 釋放C Model對象
free(student);
return 0;
}

以上代碼實現了將C Model轉換為JSON字符串的過程。需要注意的是，使用jansson庫需要在編譯時鏈接該庫，需要添加-ljansson參數。
