c 中的字符串和字符串指针有问题。在一个结构中，字符串似乎被限制为 3 个字符长;[关闭]

问：

在 addPerson（） 函数中，人群中一个人的名字似乎被限制为 3 个字符，否则它将显示前 4 个字符，后跟一些随机的 ascii 字符。我认为解决方案非常基本，但我仍在努力获得它。

最初，我让用户在主函数中输入人员的详细信息，因为我认为字符串的长度在解析函数时被限制了，但现在我认为这与存储分配有关。因此，理想情况下，我会让用户在主函数中输入人员的详细信息。 忽略 read（） 和 write（） 函数，一旦名称排序，它们就会出现

代码如下：

#include <stdio.h>
#include <stdlib.h>

struct homosapien{
    char *name;
    int age;
    char sex;
    struct person *nextPtr;
};

typedef struct homosapien person;
typedef person *personPtr;

void write();
void read();
void addPerson(personPtr *crowd);
void deletePerson(personPtr *crowd, int num);
void printPeople(personPtr crowdPtr);
void instructions();

int main()
{
    personPtr *crowd = NULL;
    //read(*crowd);
    //printPeople(crowd);
    instructions();
    char choice;

    scanf("\n%c", &choice);

    while(choice != '4'){

        switch (choice){
        case '1':
            addPerson(&crowd);
            break;

        case '2':
            if(crowd != NULL){
                int num = 1;
                personPtr temp = crowd;
                while(temp != NULL){
                    printf("\n%d  - %s", num, &temp->name);
                    temp = temp->nextPtr;
                    num++;
                }

                puts("\nEnter the number of the target");

                deletePerson(&crowd, num);
            }
            else puts("No-one to shoot");

            break;
        case '3':
            write();
            exit(0);
            break;
