To determine the output of this code given the input 'Groundhog Day [tex]$x$[/tex]', let's break down each part step-by-step:
1. Input Parsing:
- The input provided is `Groundhog Day [tex]$x$[/tex]`.
- The `cin` statement reads input. In this context, `cin [tex]${data-answer}gt;s>>$[/tex];` will read into the `string s` until it encounters whitespace and then read the first character `c` after that whitespace.
2. Input Breakdown:
- The input string "Groundhog Day [tex]$x$[/tex]" is parsed by the input statement.
- According to the usual behavior of `cin`, `s` would be assigned the value "Groundhog" since `cin` stops reading for `s` at the first whitespace.
- Then, the next part of the input is "Day [tex]$x$[/tex]", and `cin` resumes reading the next character for `c`.
3. Character Assignment:
- The first character following "Groundhog" is a space, so the next significant character is `D`.
- Therefore, `c` is assigned the value `D`.
4. Output Statement:
- The `cout [tex]${data-answer}lt;< s << c$[/tex];` statement then outputs `s` followed by `c`.
- Given our assignments from the input "Groundhog Day [tex]$x$[/tex]", `s` is "Groundhog" and `c` is `D`.
Thus, combining `s` and `c`, the output would be `GroundhogD`.
This corresponds to option d) GroundhogD.
