逐字读取文件的 C++ 程序?
在本节中,我们将看到如何使用 C++ 逐字读取文件内容。这个任务很简单。我们必须使用文件输入流来读取文件内容。文件流将使用文件名打开文件,然后使用 FileStream 加载每个单词并将它们存储到一个名为单词的变量中。然后逐个打印每个单词。
算法
read_word_by_word(filename)
begin file = open file using filename while file has new word, do print the word into the console done end
文件内容 (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
Enter filename: test_file.txt This is a test file. There are many words. The program will read this file word by word
