Question

我编写了如下代码并遇到问题。我想在我的列表中添加任务名称，但是当我输入不同的名称并尝试显示它们时，它会显示我为列表中的每个元素输入的最新名称。我怎么才能纠正？我的代码是用土耳其语写的，但我相信你明白了。（我也在评论栏中翻译）

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

struct element   // element
{
    char *taskName;  // task name
    struct element *next;  // next
};

typedef struct element Element;
typedef Element *Elementptr;

Elementptr new_element(char *taskName)  // new element
{
    Elementptr element = (Element *)malloc(sizeof(Element));
    element->taskName = taskName;
    element->next = NULL;
    return element;
}

struct stack  // stack
{
    Elementptr top;  // top
};

typedef struct stack stack;
typedef stack *stackptr;

stackptr new_stack()  // new stack
{
    stackptr stack = (stack *)malloc(sizeof(stack));
    stack->top = NULL;
    return stack;
}

Elementptr top(stackptr c)  // top
{
    return c->top;
}

int stack_empty(stackptr c)  // empty stack
{
    if (c->top == NULL)
    {
        return 1;
    }
    else
    {
        return 0;
    }
}

void stack_add(stackptr c, Elementptr new)  // add stack
{
    new->next = c->top;
    c->top = new;
}

Elementptr stack_delete(stackptr c)  // delete stack
{
    Elementptr e = c->top;
    if (!stack_empty(c))
    {
        c->top = c->top->next;
    }
    return e;
}

void stack_write(stackptr c)  // write stack
{
    printf("\n\n*** Stack'te Bulunan Gorevler ***\n");
    Elementptr p;
    int sayac = 0;
    while (!stack_empty(c))
    {
        p = stack_delete(c);
        sayac++;
        printf("\nStack d. gorevi: s\n", sayac, p->taskName);
    }
}

int main()
{
    int devam;  // continue
    char gorevIsmi[32];  // task name
    bool dogruMu = true;  // isTrue
    stackptr test = new_stack();

    printf("-- Gorev addmeyi sonlandirmak icin \"157\" giriniz --\n");   // to stop program enter 157
    do 
    {       
        printf("\nenter task name: ");  // enter task name
        scanf("s", gorevIsmi);
        Elementptr new = new_element(gorevIsmi);
        stack_add(test, new);

        printf("\nDevam durumu giriniz (Rakam): ");
        scanf("d", &devam);
        if (devam == 157)
        {
            dogruMu = false;
        }

    } while (dogruMu == true);

    stack_write(test);
}

Stacks相关链表中的一个问题
