C语言如何将一个字符串数组 写入txt 文件中 第2个“//”之前是将16进制转换为了字符串存储

fp=fopen("d:\\MYFILE.txt","wb"); fwrite(string,5,1,fp);//将string的前5个字节写入文件d:\\MYFILE.txt中 fclose(fp); 推荐使用WinHex软件查看硬盘或文件或内存中的原始字节内容。 不要把 fopen("...","...");fscanf,fprintf,fgets,fgetc,fclose //读时把\r\n替换成\n，写时把\n替换成\r\n;读到\x1a就设置EOF;读写的内容当字符看待 和 fopen("...","...b");fseek,fread,fwrite,fgetc,fclose //不作以上替换，遇到\x1a仍继续读;读写的内容当字节看待 弄混了

赞同，原来写的一个程序在文本框不能换行，后来发现是文件打开方式的问题

额 自己都有点晕啦 就是想把 几个字符串 写到一个文件里面

字符串的 数组 还是不明白怎么存储 不过 把所有的字符串串在一起 存储 中间加上了 换行和空格之类的 功能还是实现啦

fwrite(string[0],5,1,fp);//将string[0]所指内存的前5个字节写入文件d:\\MYFILE.txt中
