Question

c++ programming question! I have a string sentence. "Hello how are you" What the best way to Get each word from the sentence and assign it to a variable and then add that variable to a vector?

I won't know how many words the sentence has, only that they will be separated by a space " " delimiter. I want each word push_front(word) to the vector.

Thank you!!

#include <iostream>

#include <vector>

#include <ctime>

#include <string>

using namespace std;

int main(){

string line="hello world goodMorning";

int len = line.length();

vector<string> subArray;

// looping through the array

for (int j = 0, k = 0; j < len; j++) {

// if space found putting the string to vector

if (line[j] == ' ') {

string ch = line.substr(k, j - k);

k = j+1;

subArray.push_back(ch);

}

if (j == len - 1) {

string ch = line.substr(k, j - k+1);

subArray.push_back(ch);

}

}

// ...

for (std::vector<string>::const_iterator i = subArray.begin(); i != subArray.end(); ++i)

std::cout << *i << ' ';

return 0;
