字符串C ++的问题

我无法弄清楚如何在几个段落中阅读,而不是将每个单词放在结构中,而不是计算有多少单词。

我知道如何读取数据只是不从具有一行的字符串中传输一个单词。正如我之前所说,在几段中读到

#include <iostream>
#include <fstream>
#include <cstring>
using namespace std;


struct words
{
    char unique[21];
    int count;
} test;

void inputFile (words essay[100]);
int search (int index, int subscript, int integer,words essay[100]);

int main()
{
    words essay[100];
    inputFile (&test);

    cout << essay[0].unique<<test.count;
    return 0;
}


void inputFile (words essay[100])
{
    char fileName[81];
    char copyName[81];
    cout << "What is the name of the input file? \n";
    cin >> fileName;


    ifstream infile;
    ofstream outfile;
    int count = 0;
    char line [81];
    int ch;
    infile.open(fileName);
    outfile.open(copyName);

    while ((ch = infile.peek()) != EOF)
    {   // while not end of file
        infile.getline (line[81].unique, 81);
        cout << "Copying: " << line << endl;


        count++;
        outfile << essay << endl;
    }

    cout << "There were " << count << " lines copied\n";
    cout << endl;
    // close both files
    infile.close ();
    outfile.close ();
 };


/*int search (int index, int subscript, int integer, struct words essay[100])
{
    string key;
    key = test.unique;
    int n;
    n = test.count;
    int i;
    i = 0;
    while (i < n && essay[i] != key)
    i++;
    if (i == n)
    {
        i = -1;
    }
    return i;
    };*/

这是一个部分答案,主要侧重于清理流读取逻辑。我无法弄清楚你在做什么,有足够的清晰度来提供更多的帮助。 (例如,为什么在没有添加任何内容的情况下将essay输出到outfile。)

void inputFile (words essay[100])
{
    std::string fileName, copyName;
    cout << "What is the name of the input file?\n";
    cin >> fileName;
    // I assume you get copyName here…
    // Though fileName and copyName really should be parameters
    // passed in from `main()`.

    ifstream infile(fileName);
    ofstream outfile(copyName);
    std::string line;
    int count = 0;
    while (getline(infile, line))
    {
        cout << "Copying: " << line << endl;
        count++;
        outfile << essay << endl; // No idea what you're doing here.
    }

    cout << "There were " << count << " lines copied\n";
};
