Converting Vector of Integers to String in C

In C , converting a vector of integers to a string involves iterating through the elements and appending them to a string. A straightforward method is to use a stringstream.

<code class="cpp">#include <sstream>

std::stringstream ss;
for (size_t i = 0; i < v.size(); ++i) {
  if (i != 0) {
    ss << ",";
  }
  ss << v[i];
}
std::string result = ss.str();</code>

Alternatively, the std::for_each function allows you to achieve this in a more elegant manner:

<code class="cpp">std::string result;
std::for_each(v.begin(), v.end(), [&](int n) { result += std::to_string(n) + ","; });
result.pop_back(); // Remove the trailing comma</code>
