String Manipulation

String Tokenization

To use the C++ feature, we have to convert a string to a string stream. Then using getline() function we can do the task. The getline() function takes the string stream, another string to send the output, and the delimiter to stop the stream from scanning.

For example,

xxxxxxxxxx
24
1
#include <iostream>
2
#include <vector>
3
#include <sstream>
4

5
using namespace std;

7
int main(int argc, char *argv[])
8
{
9
    string str = "Hello, world! My name is Kyungjae Lee.";
10
    stringstream ss(str);   // convert str into string stream
11
    
12
    vector<string> tokens;
13
    string tok;
14
    
15
    // tokenize using space as a delimiter
16
    while (getline(ss, tok, ' '))
17
        tokens.push_back(temp_str);
18
    
19
    // print tokens
20
    for (auto tok : tokens)
21
        cout << tok << endl;
22
    
23
    return 0;
24
}

xxxxxxxxxx
