因此,我正在尝试完成程序的这一部分,我必须从 Stdin 读取文本文件并将其添加到“单词列表”wl 中。我知道如何从文本文件中读取,但如果有意义的话,我不知道如何将“单词”添加到列表中。所以这就是我得到的:
string getWord(){
string word;
while (cin >> word){
getline(cin, word);
}
return word;
}
void fillWordList(string source[], int &sourceLength){
ifstream in.file;
sourceLength = 50;
source[sourceLength]; ///this is the part I'm having trouble on
Source 是一个数组,用于确定从文本中读取的单词数量,length 是屏幕上打印的数量。
关于我应该从什么开始的任何想法?
编辑:这是我正在为其编写实现的程序:
#include <iostream>
#include <string>
#include <vector>
#include "ngrams.h"
void help(char * cmd) {
cout << "Usage: " << cmd << " [OPTIONS] < INPUTFILE" << endl;
cout << "Options:" << endl;
cout << " --seed RANDOMSEED" << endl;
cout << " --ngram NGRAMCOUNT" << endl;
cout << " --out OUTPUTWORDCOUNT" << endl;
}
string source[250000];
vector<string> ngram;
int main(int argc, char* argv[]) {
int n, outputN, sl;
n = 3;
outputN = 100;
for (int i = 0; i < argc; i++) {
if (string(argv[i]) == "--seed") {
srand(atoi(argv[i+1]));
} else if (string(argv[i]) == "--ngram") {
n = 1 + atoi(argv[i+1]);
} else if (string(argv[i]) == "--out") {
outputN = atoi(argv[i+1]);
} else if (string(argv[i]) == "--help") {
help(argv[0]);
return 0; }
}
fillWordList(source,sl);
cout << sl << " words found." << endl;
cout << "First word: " << source[0] << endl;
cout << "Last word: " << source[sl-1] << endl;
for (int i = 0; i < n; i++) {
ngram.push_back(source[i]);
}
cout << "Initial ngram: ";
put(ngram);
cout << endl;
for (int i = 0; i < outputN; i++) {
if (i % 10 == 0) {
cout << endl;
}
//put(ngram);
//cout << endl;
cout << ngram[0] << " ";
findAndShift(ngram, source, sl);
} }
我应该将其用作参考,但它对我没有太大帮助。
