Phone 号码列表

Phone Number Lsit

用 C++ 编写一个简单的 telephone 目录程序,在包含姓名列表和 phone 号码的文件中查找 phone 号码。应提示用户输入名字和姓氏,然后程序输出相应的数字,或者指示该名称不在目录中。每次查找后,程序应询问用户是否要查找另一个号码,然后重复该过程或退出程序。文件中的数据应进行组织,以便每行包含一个名字、一个姓氏和一个 phone 数字,以空格分隔。您可以 return 关闭文件并再次打开它来回到文件的开头。

我无法接通电话 检查= strstr(phone目录,名称); 工作 strstr 部分不断给出错误:没有重载函数的实例 "strstr" 与参数列表参数类型匹配。

这是我的代码的副本:

#include <iostream>
#include <string>
#include <fstream>
#include <cstring>

using namespace std;

int arraySize();

 int main()
{
    const int SIZE = arraySize();

    char *phoneDirectory;
    int size=0;
    char name; //name to look for
    char *check = NULL;
    bool find = false;

    phoneDirectory = new char [SIZE];

    ifstream phoneNumbers;
    phoneNumbers.open("phoneNumbers.txt");

    if (!phoneNumbers)
        cout << "Error opening data file\n";

    //looping throught the name file
    else
    {
        for (int i = 0; i < SIZE; i++)
        {
            phoneNumbers >> phoneDirectory;
        }

        phoneNumbers.close();       //closes data file
    }

    phoneNumbers.close();

    // Get a name or partial name to search for.
    cout << "Enter a name or partial name to search for: ";
    cin.getline(phoneDirectory, name);

    cout << "\nHere are the results of the search: " << endl;
    int entries = 0;

    for (int i = 0; i < size; i++)
    {
        check = strstr(phoneDirectory, name);

        if (check != NULL)
            find = true;
    }

    if (!find) 
        cout << "No matches!" << endl;


    delete [] phoneDirectory;
    return 0;
} 

 int arraySize()
{
    string phoneNum;
    int size = 0;

    ifstream phoneNumbers;      // Input file stream object

    // Open the data file.
    phoneNumbers.open("phoneNumbers.txt");
    if (!phoneNumbers)
        cout << "Error opening data file\n";

    //looping throught the name file
    else
    {
        while (getline(phoneNumbers, phoneNum))
        {
            size++;
        }
        phoneNumbers.close();       //closes data file
    }
    return size;
}

您的 name 变量是 char。应该改为 char* 吗?
