could anyone tell me or point me to a simple example of how to append an int to a stringstream containing the word "Something" (or any word)?

To concatenate a string to an int value, use the concatenation operator. Here is our int. int val = 3; Now, to concatenate a string, you need to declare a string and use the + operator.
Using to_string() function The most commonly used approach to concatenate an integer to a string object in C++ is to call the std::to_string function, which can return the string representation of the specified integer.
In C++, the stoi() function converts a string to an integer value. The function is shorthand for “string to integer,” and C++ programmers use it to parse integers out of strings. The stoi() function is relatively new, as it was only added to the language as of its latest revision (C++11) in 2011.
The StringStream class in C++ is derived from the iostream class. Similar to other stream-based classes, StringStream in C++ allows performing insertion, extraction, and other operations. It is commonly used in parsing inputs and converting strings to numbers, and vice-versa.
stringstream ss;
ss << "Something" << 42;
