parse string to vector of int

Question

I have a string which contains some number of integers which are delimited with spaces. For example

string myString = "10 15 20 23"; 

I want to convert it to a vector of integers. So in the example the vector should be equal

vector<int> myNumbers = {10, 15, 20, 23}; 

How can I do it? Sorry for stupid question.

Answer 1

You can use std::stringstream. You will need to #include <sstream> apart from other includes.

#include <sstream> #include <vector> #include <string>  std::string myString = "10 15 20 23"; std::stringstream iss( myString );  int number; std::vector<int> myNumbers; while ( iss >> number )   myNumbers.push_back( number );
