获取交换功能的分段错误 11

Question

我正在创建一个带有指针的交换（在我的实际程序中实现它之前使用 couts 对其进行测试）函数，我不完全确定为什么我在运行它时会遇到这个分段错误。有什么想法吗？

#include <iostream>
#include <stdio.h>
#include <stdlib.h>
using namespace std;

char * initializeWord(int length);
void swap(char *a, char *b);
//void scrambleWord(char *word, int size);

int main()
{
    int length;
    char *word, *x, *y;
    cout << endl << "Welcome to Word Scrambler!" << endl << endl;
    cout << "How many letters will your word have?" << endl << endl;
    cin >> length;
    getchar();
    cout << endl << "Please input a word that contains " << length << " many characters." << endl << endl;
    word = initializeWord(length);
    cout << endl;
    cout << "The word you entered was: " << word << endl << endl;
    swap(x,y);

    delete[] word;
    return 0;
}

char * initializeWord(int length)
{
    //initialization of char array
    char *cArray = new char[length];
    //user's word
    cin >> cArray;
    getchar();

    return cArray;
    delete[] cArray;
}

void swap(char *a, char *b) 
{
    cout << "First values:" << endl << a << endl << b << endl;
    char *temp = a;
    a = b;
    b = temp;
    cout << "Second values:" << endl << a << endl << b << endl;
}

Answer 1

cin >> cArray; 此行将用户输入设置为数组的地址。

你可能想要：

char* initializeWord(int length)
{
   char* cArray = new char[length];

   for(int i = 0; i < length; ++i)
   {
        cin >> cArray[i]
   }
   ...
}

或者只使用字符串。
