获取交换功能的分段错误11

Getting a segmentation fault 11 for swap function

本文关键字：错误 分段 交换 功能 获取      更新时间：2023-10-16

我正在创建一个互换（在我的实际程序中实现它之前使用couts对其进行测试），我不确定为什么当我在我运行。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;
}

cin>> carray;该行将用户输入为您的数组的地址。

您可能想要：

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

或仅使用字符串。
