Inputs are ASCII under the default C locale. The text is the last field of each record because INPUT into a STRING reads the rest of the line; empty text is still encoded with a flag so that every record has a visible text field. Substrings remain in range; zero width is a documented project boundary. Each record produces exactly one output line. Random records are preceded by fixed boundary records; every arithmetic intermediate is bounded. diff --git a/tests/ii/strings/program.cps b/tests/ii/strings/program.cps index 55e7541..8a5e509 100644 --- a/tests/ii/strings/program.cps +++ b/tests/ii/strings/program.cps @@ -7,9 +7,9 @@ DECLARE Width : INTEGER INPUT Count FOR Index <- 1 TO Count INPUT Empty - INPUT Text INPUT Start INPUT Width + INPUT Text IF Empty = 1 THEN Text <- "" ENDIF diff --git a/tests/ii/strings/reference.cc b/tests/ii/strings/reference.cc index 54d6efc..ec67b8c 100644 --- a/tests/ii/strings/reference.cc +++ b/tests/ii/strings/reference.cc @@ -8,7 +8,10 @@ int main() { for (int i = 0; i < count; ++i) { int empty, start, width; std::string text; - if (!(std::cin >> empty >> text >> start >> width)) return 1; + if (!(std::cin >> empty >> start >> width)) return 1; + // The text is the rest of the line, as for INPUT into a STRING. + if (!std::getline(std::cin >> std::ws, text)) return 1; + if (!text.empty() && text.back() == '\r') text.pop_back(); if (empty) text.clear(); auto lower = text, upper = text; for (auto &c : lower) c = static_cast<char>(std::tolower(static_cast<unsigned char>(c))); |
