c语言中fprintf_c语言输出函数printf

/*
*描述：fputs 函数是向指定的文件写入一个字符串
*
*参数：
*   [in]  stream： 文件指针句柄;
*   [in]  format： 格式化字符串，与 printf 函数一样;
*
*返回值：如果成功，该函数返回一个非负值，如果发生错误则返回 EOF(-1)。
*/

int fprintf (FILE* stream, const char*format, [argument]);

//示例：
fprintf(stream,"www.codersrc.com\n");
fprintf(stream,"www.codersrc.com age:%d\n",17);
fprintf(stream,"www.codersrc.com age:%d name:%s\n",17, "zhangsan");
fprintf(stream,"www.codersrc.com age:%d name:%s height:%f\n",17, "zhangsan",1.75);
