Split a line read from a file in C++ - c++

Question

How do I access individual elements of a line read from a file?
I used the following to read a line from a file:
getline(infile, data) // where infile is an object of ifstream and data is the variable where the line will be stored
The following line is stored in data : "The quick brown fox jumped over the lazy dog"
How do I access particular elements of the line now? What if I want to play around with the second element ( quick ) of the line or get hold of a certain word in the line? How do I select it?
Any help will be appreciated

Answer 1

data = "The quick brown fox jumped over the lazy dog" and the data is string , your string delimeter is " ",you can use std::string::find() to find the position of the string delimeter and std::string::substr() to get a token:
std::string data = "The quick brown fox jumped over the lazy dog";
std::string delimiter = " ";
std::string token = data.substr(0, data.find(delimiter)); // token is "the"

Answer 2

Since your text is space separated, you can use std::istringstream to separate the words.
std::vector<std::string> words;
const std::string data = "The quick brown fox jumped over the lazy dog";
std::string w;
std::istringstream text_stream(data);
while (text_stream >> w)
{
words.push_back(w);
std::cout << w << "\n";
}
The operator>> will read characters into a string until a space is found.
