Response

Rationale


1.2 Technical Requirements

Question 23: Are distinctions of case ignored in external identifiers?

Response

Rationale


Question 24: What conversion rules are applied when converting an integral type to a floating type which cannot represent the result exactly?

Response

Rationale


Question 25: What conversion rules are applied when converting a double to a float or a long double to a long float which cannot represent the result exactly?

Response

Rationale


Question 26: What truncation rules are applied when using the division operator and either of the operands is negative?

Response

Rationale


Question 27: What sign is given to the result when using the remainder operator and either of the operands is negative?

Response

Rationale


Question 28: When mapping sequences of characters to external source file names, does the implementation ignore distinctions of alphabetic case and restrict the mapping to 6 significant characters?

Response

Rationale
