These objects could represent anything from a person with a name and address to smaller programs like widgets. OOP is particularly useful for big, complex programs or projects that need regular updates. For example, consider you’re building a virtual world on a computer. In this world, every...
linux内核中的堆栈回朔,是跟架构相关的,而linux, arm的堆栈回朔函数为:arch/arm/kernel/traps.c [cpp]view plaincopy staticvoiddump_backtrace(structpt_regs *regs,structtask_struct *tsk) { unsignedintfp, mode; intok = 1; printk("Backtrace: "); if(!tsk) tsk = current; if(regs) { fp = r...
下面就来显示如何定位出出错代码行: 1.首先,编译时打开complie with debug info选项,步则如下 make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- menuconfig 进入Kernel hacking 选择Compile the kernel with debug info 然后,保存,退出。 接着make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- 编译, 等编...
Here, repeatedly invokes the function or function object passed to it with sequential numbers in the range [1,20]. You can see in that the loop's body is tightly coupled with the looping logic, but in these have been decoupled using the template. The loop's body is implemented as a ...
The first such OOPL to be invented was SIMULA, and the most widely used OOPL today is C++, which is a derivative of the C language with added object-oriented features. Other important OOPLs include JAVA, OBJECT PASCAL, EIFFEL, and the historically important SMALLTALK. [Read more…] about ...
In function overloading we can have more than one function with same name but different numbers, type or sequence of arguments. Polymorphism Example #include<iostream>usingnamespacestd;classSum{public:intadd(intnum1,intnum2){returnnum1+num2;}intadd(intnum1,intnum2,intnum3){returnnum1+num...
This repo is created to help people with the machine coding interview. There is no free website to provide complete guide for machine coding round so I have created this repo where I have shared all my machine coding practices and created a medium post as well to help with theory part. ...

14. Because friend functions are inherited, deriving a class from a base class with friends can violate the encapsulation of the derived class. True False 15. When deriving from a private base class, the public, protected and private members of the base class become private members of the der...
1、修改你的BoardConfig.mk...FakeCamera.cpp->UsbCamera.cpp 目前只实现了基本功能 该文件可以按照V4L2流程来写 网上也有现成的patch,使用mmap方式,可惜是1.6的,没编译过去,待研究 1)构造函数中进行初始化 usb gadget uvc driver的code分析 gadget侧两个driver。host侧的driver在v4l2框架下,而设备侧的driver在usb...
