String Stream stringstream for Parsing

Use std::stringstream to tokenize and parse text into typed values.

What is a stringstream?

std::stringstream wraps a string in an iostream interface. Read and write to it with >> and << as if it were cin or cout.

#include <sstream>
std::stringstream ss;

Use it to build complex strings from mixed types. Call .str() to get the result.

std::stringstream out;
out << "User: " << name << ", Age: " << age;
std::string result = out.str();
