我根据书本改编来的，但出现了几个问题：
1。加了邮编等属性后显示通信录时无法对齐，试了好久也没弄好。
2.存盘后读取文件，文件名老是错。。。
3。我换成txt存盘后出现"烫烫烫。。。的乱码"，只能存入姓名，之后全是乱码,是不是要初始化一下。
请高手指点

没人帮我解决一下吗.....

[hanyuwei0]

帮定下，可能都嫌代码太长了

[猫已经找不回了]

2进制模式打开文件操作看看

[九度空间]

没时间看

[ztenv]

你要初始化你的数据段，一开始就要清空，注意字串的结尾符。。。。。。

[anniue]

好长的代码， 如果出现烫烫那么肯定是内存未初始化 用memset(str,0x0,sizeof(str)),至于对不齐，怎么没看到list 函数对齐是不是有点问题撒下面是将格式处理好的，你看下：

能不能用 "\t"在输出的时候使它对齐

[lynjimmy]

\t 和\n 我试了，都不能，等了这么久终于有人回答了，感激。。。
