taking input of a string word by word

Question

I just started learning C++. I was just playing around with it and came across a problem which involved taking input of a string word by word, each word separated by a white

Answer 1

Put the line in a stringstream and extract word by word back:

#include 
#include 
using namespace std;

int main()
{
    string t;
    getline(cin,t);

    istringstream iss(t);
    string word;
    while(iss >> word) {
        /* do stuff with word */
    }
}

Of course, you can just skip the getline part and read word by word from cin directly.

And here you can read why is using namespace std considered bad practice.
