Understanding Programming Languages

This ebook compares constructs from C with constructs from Ada by way of degrees of abstractions. learning those languages presents a company beginning for an in depth exam of object-oriented language aid in C++ and Ada ninety five. It explains what possible choices can be found to the language fashion designer, how language constructs can be utilized in phrases of defense and clarity, how language constructs are applied and which of them should be successfully compiled and the function of language in expressing and imposing abstractions.

Example text

Processor instructions vary somewhat from one computer to another. The processor of a modern computer can have as many as several hundred available instructions. However, these instructions are typically all about as simple as those we have just described. Software You do not normally talk directly to the computer, but communicate with it through an operating system. The operating system allocates the computer’s resources to the different tasks that the computer must accomplish. The operating system is actually a program, but it is perhaps better to think of it as your chief servant.

First, eight is a power of 2. ) Since computers use bits, which have only two possible values, powers of 2 are more convenient than powers of 10. Second, it turns out that eight bits (one byte) are required to code a single character (such as a letter or other keyboard symbol). 5 6 Chapter 1 / Introduction to Computers and C++ Programming The memory we have been discussing up until now is the main memory. Without its main memory, a computer can do nothing. However, main memory is only used while the computer is actually following the instructions in a program.

In its most general sense, it means any information available to the computer. The word is commonly used in both the narrow sense and the more general sense. High-Level Languages There are many languages for writing programs. In this text we will discuss the C++ programming language and use it to write our programs. C++ is a high-level language, as are most of the other programming languages you are likely to have heard of, such as C, C#, Java, Python, PHP, Pascal, Visual Basic, FORTRAN, COBOL, Lisp, Scheme, and Ada.
