How Can I Efficiently Separate Comma-Delimited Strings in C ?

Separating Comma-Delimited Strings Using Stringstream

In the provided problem, the task is to separate a comma-delimited string into individual tokens. While the stringstream::operator can effortlessly separate words by spaces, it falls short when it comes to commas.

To overcome this challenge, we employ a modified approach:

#include <iostream>
#include <sstream>

int main() {
  std::string input = "abc,def,ghi";
  std::istringstream ss(input);
  std::string token;

  // Use getline to separate by commas
  while (std::getline(ss, token, ',')) {
    std::cout <p>In this modified code:</p>
<ul>
<li>We use std::getline instead of std::stringstream::operator>>. getline can extract substrings up to a specified delimiter (in this case, a comma).</li>
<li>We iterate over the input stream until no more tokens are found.</li>
<li>For each token, we print it on a new line.</li>
</ul>
<p>The output accurately separates the input string into individual tokens:</p>
<pre class="brush:php;toolbar:false">abc
def
ghi
