[C/C++] 把结构体写入到文件，再从文件读取到结构体

 

#include #include struct example      {       int num;        char name[16];    }; int main()    {     example test;     example read;        FILE *fp;     test.num = 1;        strcpy(test.name, "Hello World!");     fp = fopen("file.dat", "w+");     if (!fp)     {         printf("open file error!");         return -1;     }     rewind(fp);     fwrite(&test, sizeof(example), 1, fp);     rewind(fp);     fread(&read, sizeof(example), 1, fp);     printf("%d, %s/n", read.num, read.name);     fclose(fp);     return 0;
