Android 读取和存储json文件代码

你可以使用以下代码读取和存储json文件：

读取json文件：

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

#define MAX_JSON_SIZE 1024

int main() {
    FILE *fp;
    char json[MAX_JSON_SIZE];
    fp = fopen("data.json", "r");
    if (fp == NULL) {
        printf("Failed to open file\n");
        return 1;
    }
    fgets(json, MAX_JSON_SIZE, fp);
    fclose(fp);
    printf("%s\n", json);
    return 0;
}

存储json文件：

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

#define MAX_JSON_SIZE 1024

int main() {
    FILE *fp;
    char json[MAX_JSON_SIZE] = "{\"name\":\"John\",\"age\":30,\"city\":\"New York\"}";
    fp = fopen("data.json", "w");
    if (fp == NULL) {
        printf("Failed to open file\n");
        return 1;
    }
    fputs(json, fp);
    fclose(fp);
    return 0;
}
