C ++程序逐字读取文件？
在本节中，我们将看到如何使用C++逐字读取文件内容。任务很简单。我们必须使用文件输入流来读取文件内容。文件流将通过使用文件名打开文件，然后使用FileStream加载每个单词并将其存储到一个名为word的变量中。然后逐个打印每个单词。
算法
read_word_by_word（文件名）
begin
file = open file using filename
while file has new word, do
print the word into the console
done
end档案内容(test_file.txt)
This is a test file. There are many words. The program will read this file word by word
示例
#include<iostream>
#include<fstream>
using namespace std;
void read_word_by_word(string filename) {
fstream file;
string word;
file.open(filename.c_str());
while(file > word) { //take word and print
cout << word << endl;
}
file.close();
}
main() {
string name;
cout << "Enter filename: ";
cin >> name;
read_word_by_word(name);
}输出结果
Enter filename: test_file.txt This is a test file. There are many words. The program will read this file word by word
