1.1 Scope of the Implementation

Question 1: What is the limit on the number of nesting levels of compound statements, iteration control structures and selection control structures?

Response

Rationale


Question 2: What is the limit on the number of nesting levels of conditional inclusions?

Response

Rationale


Question 3: What is the limit on the number of pointer, array and function declarators (in any combination) modifying an arithmetic, a structure, a union or an incomplete type in a declaration?

Response

Rationale


Question 4: What is the limit on the number of nesting levels of parenthesised declarators within a full declarator?

Response

Rationale


Question 5: What is the limit on the number of nesting levels of parenthesised expressions within a full expression?

Response

Rationale


Question 6: What is the number of significant initial characters in an internal identifier or macro name?

Response

Rationale


Question 7: What is the number of significant initial characters in an external identifier?

Response

Rationale


Question 8: What is the limit on the number of external identifiers in one translation unit?

Response

Rationale


Question 9: What is the limit on the number of identifiers with block scope declared within one block?

Response

Rationale


Question 10: What is the limit on the number of macro identifiers simultaneously defined in one translation unit?

Response

Rationale


Question 11: What is the limit on the number of parameters in one function definition?

Response

Rationale


Question 12: What is the limit on the number of arguments in one function call?

Response

Rationale


Question 13: What is the limit on the number of parameters in one macro definition?

Response

Rationale


Question 14: What is the limit on the number of arguments in one macro invocation?

Response

Rationale


Question 15: What is the limit on the number of characters in a logical source line?

Response

Rationale


Question 16: What is the limit on the number of characters in a character string literal or wide string literal (after concatenation)?

Response

Rationale


Question 17: What is the limit on the number of bytes in an object (in a hosted environment only)?

Response

Rationale


Question 18: What is the limit on the number of nesting levels for #included files?

Response

Rationale


Question 19: What is the limit on the number of case labels for a switch statement (excluding those for any nested switch statement)?

Response

Rationale


Question 20: What is the limit on the number of members in a single structure or union?

Response

Rationale


Question 21: What is the limit on the number of enumeration constants in a single enumeration?

Response

Rationale


Question 22: What is the limit on the number of levels of nested structure or union definitions in a single struct-declaration-list?

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
