我将如何 go 关于使用 C++ 将纯文本文件中的单词存储到数组中？

Question

I've been tasked with writing a C++ program that opens a text file, determines the length of each word, then produces output stating how many times a particular word length occurs.
I've figured how to open and read the contents of the file.

How would I take each word and store them in an array?

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

using namespace std;


void getFile(string);

void getFile(string filename)
{
    string array[2]; 
    short loop = 0; 
    string line; 
    ifstream myfile (filename); 
    if (myfile.is_open()) 
    {
        while (!myfile.eof() ) 
        {
            getline (myfile,line); 
            array[loop] = line;
            cout << array[loop] << endl; 
            loop++;
        }
        myfile.close(); 
    }
    else{
        cout << "can't open the file"; 
        system("PAUSE");
    } 
    
}

int main(){
    string fileName;
    while (true){
        cout << "\nEnter the name of a file: ";
        getline(cin, fileName);
        
        if (fileName == ""){
            cout << "Invaled file name, enter another!!!"<<endl;
            main();
        }
        else{
            getFile(fileName);
        }
    }
    
    return 0;
}

Answer 1

You do not store words in an array.
You only need to store the word lengths and how often each of them occurred.
If you have a guaranteed and low maximum word length you can even simplify by using an array where the length of the current word is used as an index. Init all entries with 0. Then count entries up when the corresponding word length occurs.
