C 未在while循环中注册字符

我不明白为什么我的while循环在输入时找不到#。我希望当我在

输入name:

下输入时，循环中断，这样

e.name

将具有

当我尝试它时，循环永远不会结束，但是

e.name

将包含

#

---

在您的while声明中：

while(e.name[0] != "#")

您正在将字符与指针进行比较。指针是字符串“#”的内存地址。您必须将代码更改为：

while(e.name[0] != '#')

有很多问题，但这应该让你开始，有时确保所有的空白（空格、换行符、标签等）都被使用是一项挑战

// My guess at employee structure
typedef struct
{
    char name[100];
    char telno[25];
    int id;
    double salary;
} Employee;

// NOTE: MSVC "forces" me to use safe version of some funtions: "_s" suffix

int readin(Employee *p)
{
    Employee e = *p;
    int count = 0; // <-- Never used

    char line[80];

    // Why are you looping, you only ever modify 1 employee?
    while (e.name[0] != '#') // <- Fixed comparison
    {
        printf("Enter name:\n");
        //scanf("\n"); <- Not needed
        gets_s(e.name);
        //*Test for '#' here and exit loop before entering other fields?

        printf("Enter tel:\n");
        //scanf("\n"); <- Not needed
        //scanf_s("%s", &e.telno, 25);
        gets_s(e.telno, 25);

        //scanf("\n"); <- Not needed
        //scanf_s("%d", &e.id);

        gets_s(line, sizeof(line));
        sscanf_s(line, "%d", &e.id);

//我对员工结构的猜测
类型定义结构

字符名[100]；
char-telno[25]；
int-id；
双薪；
}员工；
//注意：MSVC“强制”我使用一些函数的安全版本：“\u s”后缀
int readin（员工*p）
{
雇员e=*p；
int count=0；/
e.name[0]！=“#”

e.name[0]！=“#”
。不要使用
gets
而是使用
fgets
。
scanf（%s），&e.telno）
scanf（%s），e.telno）
（我想最好）。scanf
scanf（“\n”）
的意思是
scanf（“\n”）
