I\'ve been reading quite many on the Internet and it seems that many people mentioned the following rules (but i couldn\'t find it in the standard),
This is the whole code. Upon compiling I get the error below: error LNK2019: unresolved external symbol \"void __cdecl CandyBarFunc(struct CandyBar &,char const *,double,int)\" (?CandyBarFunc@@Y
In C++, pre-increment operator gives lvalue because incremented object itself is returned, not a copy.
When programming in C++03, we can\'t pass an unnamed temporary T() to a function void foo(T&);.The usual solution is to give the temporary a name, and then pass it like:
gcc is giving me invalid lvalue in assignment errors for: -2[(size_t *)new] = 0; Changing the code to the following makes it开发者_如何学编程 go away:
[array objectAtIndex:i]开发者_运维技巧 doesn\'t work as an L value, so it can\'t be used to set the object at index i.Use -insertObject:atIndex: or replaceObjectAtIndex:withObject:.
What is the difference between: const double& pi 开发者_运维问答= 3.14; and (no ampersand): const double pi = 3.14;
const and volatile are called cv-qualifier by the C spec. What is exactly defference between specifier and qualifier (cv-qualifier)? Is a qualifier is a specifier as well?
I ran into my first compiler that changes the lvalue passed to ::delete, but doesn\'t zero out the lvalue. That is the following is true:
I get the error (L开发者_运维技巧value required as left operand of assignment) for this code: [[addAlertViewController alertsArray] = [NSMutableArray arrayWithObjects:nil] retain];
