Is there a way to avoid c开发者_如何转开发opying large vectors, when a function expects a vector with (pointer to) baseclass objects as input but I only have a vector of (pointers to) derived objects?
#define PORTC *(unsigned char volatile *)(0x1003) #define DDRC *(unsigned char volatile *)(0x1007) So I\'ve been trying to read some stuff about embedded C. Initially I thought this macro was a poin
I\'m writing a generic wrapper around a software\'s GUI API which has the ability to process quite a few of its own \'built-in\' types but I can\'t figure out how to get it what it needs. For example,
In my code i have the following code: Order = config.DeploymentSteps.Select(x => x.Order).DefaultIfEmpty().Max() + 1;
I want to test whether a given object can be cast to a given Type. In this scenario, I have an object, and the Type representing what type I want to cast it to:
I already have a solution, but I don\'t like it. Also, it would be nice to know your thoug开发者_运维知识库hts about this.
I searched around and couldn\'t find any examples doing this, though this was helpful: Create Generic method constraining T to an Enum
As title says, I\'m currently doing some small hacks with pointers in C++, but something isn\'t working out here\'s what I got:
I have program that currently use typecast for a null-pointer vector开发者_JS百科 according to the following:
std::cout << (DWORD)\"test\"; If I compile an开发者_Go百科d run this I get different output values each time, but I can\'t figure out why.
