用C ++编写一个简单的电话目录程序,在一个包含姓名和电话号码列表的文件中查找电话号码。应提示用户输入名字和姓氏,然后程序输出相应的号码,或者表示该名称不在目录中。在每次查找之后,程序应该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。应组织文件上的数据,以便每行包含由空格分隔的名字,姓氏和电话号码。您可以通过再次打开它来返回文件的开头。

我不能排队         check = strstr(phoneDirectory,name); 工作strstr部分继续给出错误:没有重载函数的实例" strstr"匹配参数列表参数类型。

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。应该是char*吗?
