C++ program to read file word by word
Given a text file, extract words from it. In other words, read the content of file word by word. Example :
Input: And in that dream, we were flying.
Approach : 1) Open the file which contains string. For example, file named “file.txt” contains a string “geeks for geeks”. 2) Create a filestream variable to store file content. 3) Extract and print words from the file stream into a string variable via while loop.
string word, t, q, filename;
filename = "file.txt";
(file >> word)
cout << word << endl;
Time Complexity: O(N) // going through the entire file
Auxiliary Space: O(1)
