C++ program to read file word by word?
In this section we will see how we can read file content word by word using C++. The task is very simple. we have to use the file input stream to read file contents. The file stream will open the file by using file name, then using FileStream, load each word and store it into a variable called word. Then print each word one by one.
Algorithm
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
File Content (test_file.txt)
This is a test file. There are many words. The program will read this file word by word
Example
#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);
}Output
Enter filename: test_file.txt This is a test file. There are many words. The program will read this file word by word
