C _Static_assert(constant-expression,string-literal);static_assert(constant-expression,string-literal); parameters constant-expression 可在编译时计算的整型常数表达式。 如果表达式为零 (false),则显示string-literal参数,并且编译因出错而失败。 如果表达式不为零 (true),则不会产生任何影响。
When the input is a type for which a suitable built-in binary relational operator is defined that is applicable with the input as its left operand and the given constant as its right operand, the evaluation of that operator is taken as the meaning of the relational pattern. Otherwise we...
