The most elegant way to iterate the words of a string using C++
There is no one elegant way to iterate the words of a C/C++ string. The most readable way could be termed as the most elegant for some while the most performant for others. I've listed 2 methods that you can use to achieve this. First way is using a stringstream to read words separated by spaces. This is a little limited but does the task fairly well if you provide the proper checks. For example,>
Example Code
#include <iostream>
#include <vector>
#include <string>
#include <sstream>
using namespace std;
int main() {
string str("Hello from the dark side");
string tmp; // A string to store the word on each iteration.
stringstream str_strm(str);
vector<string> words; // Create vector to hold our words
while (str_strm >> tmp) {
// Provide proper checks here for tmp like if empty
// Also strip down symbols like !, ., ?, etc.
// Finally push it.
words.push_back(tmp);
}
for(int i = 0; i<words.size(); i++)
cout << words[i] << endl;
}Output
Hello from the dark side
