程序运行出来后，添加职工信息的时候出错，希望好心人帮解决！

希望大神们帮解决！

有没有大神呀

printf的格式有问题，%与参数要一一对应，好好检查一下。编译时也有相关告警的。,scanf也是

[此贴子已经被作者于2016-6-23 09:18编辑过]

在C++运行的时候没有报错，，运行出来进入添加模块的时候报错！应该不是这的问题吧

void append()里的
fprintf(fp,"%-20s%-20s%-20c%-20d%-20s%-20f%-20c%-20s%-20s\n",empinfo.jobno,empinfo.name,empinfo.sex,empinfo.age,empinfo.edulevel,empinfo.salary,empinfo.addr,empinfo.tel);这句有问题。估计这就是造成添加职工信息出错的主要原因。

还能具体点吗？我才开始接触C语言，许多地方不懂。

你的结构体才8组数据，你输出写到9组数据，由于你多写的一组输出格式，导致输出的格式对不上了。输出是自右向左处理数的。
这个错误编译系统是不会发现的，要你自己发现。

char jobno[10];
    char name[20];
    char sex;
    int age;  
    char edulevel[10];
    float salary;
    char addr;    //这里定义的addr是字符型，你后面输出的却是%s
    char tel[11];

另外你打开的文件只有文件名，不需要增加路径吗？
