Assembly language programming

In its role as a high level assembler used for writing operating systems, C is often used to access memory locations and change individual bits. You might for example need to access individual bits in an int. It can sometimes be useful to conserve memory by using a byte to hold 8 flags though with an abundance of ram it's common to just use one byte per flag or even one per int. Knowing how to extract or alter individual bits is still worthwhile knowing; you may never have to use it but when you have to maintain code that...

I have noticed over the years that students have great deal of difficulty dealing with composite and abstract data types. Therefore we are going spend an extra lab review material we have already learned. Vector data type, a variation of array, will be introduced as well. Vector data type (Vector Class) can be used when you need an array that grows dynamically. However, C++ does not allow us to declare size of an array dynamically like some other languages. It is important for you to declare the maximum size you will need. Suppose you are writing a program to keep...

When instructions within a program are executed one after the other sequentially that program is said to have a linear structure. Decision making after examining all available options is very important in life as well as in programming. For example, it is the law that all males 18 or older should register with the selective service. If you are writing a program to send out reminders to enforce this law, the decision to send the letter should be based on if a person is male and if he is 18 or older. In this chapter you will learn how to...

Lập trình hợp ngữ (assembly language programming) cho họ vi điều khiển MCS51. Một chương trình viết bằng hợp ngữ (chương trình hợp ngữ) là chương trình được viết bằng việc sử dụng các câu lệnh trong tập lệnh của họ vi điều khiển với các mã lệnh dưới dạng mã gợi nhớ. Chương trình hợp ngữ thường được gọi là chương trình nguồn hay mã nguồn được một chương trình biên dịch (chương trình dịch) dịch ra thành ngôn ngữ máy dưới dạng mã nhị phân và được nạp vào bộ nhớ chương trình của vi điều khiển thông qua một máy nạp chương trình (Programmer)....
