Affected rules

  • A5-16-1: cpp/autosar/ternary-conditional-operator-used-as-sub-expression

Rule A5-16-1 (required, implementation, automated)
The ternary conditional operator shall not be used as a sub-expression.

Description

When initializing a string inside a ternary expression, A5-16-1 error is triggered.
I tried with std::uint32_t and with a class, and the error was not triggered.

Example

std::string const str{cond ? "str1" : "str2"}; // Triggers A5-16-1

Test const test{cond ? Test() : Test()}; // Ok
std::uint32_t const nb{cond ? 0 : 1}; // Ok
