Converting a string into a vector means transforming textual data into a structured list of elements (words, tokens, or numerical features) that can be processed programmatically. The approach depends on the context — whether you’re working with C++/Java collections or NLP vector embeddings.
1. Splitting Strings into Vectors (C++ Example) A common case is splitting a delimited string into a vector<string>.
#include <bits/stdc++.h>using namespace std;vector<string> split(string str, char delimiter) {stringstream ss(str);vector<string> res;string token;while (getline(ss, token, delimiter)) {res.push_back(token);}return res;}int main() {string s = "GeeksforGeeks is a computer science portal";vector<string> words = split(s, ' ');for (auto &w : words) cout << w << endl;}Copied!✕CopyHow it works:
stringstream treats the string as a stream.
getline extracts tokens separated by the delimiter.
Tokens are pushed into a vector.
