i'm looking @ past paper course i'm doing @ university, , there question c pointers. i reckon have reasonable grasp of how work, question confusing me: consider running c program fragment: int x[4] = {0,2,4,6}; int *y; y = &x[2]; *(x + 2) = y[1] + 1; value of expression *y afterwards? (a) 2 (b) 4 (c) 5 (d) 7 (e) 8 now, in answers said question, says answer d . i'm super confused, seeing as: the value of x not declared, i'd have thought impossible evaluate x+2 y isn't array, how can y[1] evaluated? why 7 correct answer here? lets break down: int x[4] = {0,2,4,6}; x [0] = 0 x [1] = 2 x [2] = 4 x [3] = 6 int *y; pointer integer y point location in x x [0] = 0 // <-- y ? x [1] = 2 // <-- y ? x [2] = 4 // <-- y ? x [3] = 6 // <-- y ? y = &x[2]; have specified y points x[2] x [0] = 0 x [1] = 2 x [2] = 4 // <-- y (or y[0]) x [3] = 6 *(x + 2) same x[2] so: x[2] = y[1] + 1...

for debugging purposes, output html comment indicating filename of current cshtml file @ beginning , end of every cshtml file. for example, i'd when view source of generated webpage, see this: <!-- begin _layout.cshtml --> ... headings , such ... <!-- begin about.cshtml --> ... generated content about.cshtml ... <!-- end about.cshtml --> ... footers , such ... <!-- end _layout.cshtml --> i'm new platform, i'm not sure right terminology this, let alone in api look. i'm hoping @ least can edit of cshtml files , reference object @ runtime contains filename property, in syntax similar to: <!-- begin @object.optionalproperty.optionalsubproperty.filename --> or, alternatively, way modify rendering engine automatically @ beginning , end of every rendered file. thank time , responses.

this silly question. lot of data extrapolation for loops in applications. in cases tend find i <= 2 easier read/interpret i < 3 . based on know should mean same thing, i'm wondering if there special cases evaluated differently when used in for loop. example, if used ++i instead of i++ . provided i integer, expressions i<=2 , i<3 should identical in function. (they may different in terms of speed performance) if i has type float , double , decimal , or related, value of 2.3 fail first test, pass second test. if overload operator< or operator<= , make possible.
