2018-10-31 13:58:46 Variables and Other References

A Python program accesses data values through references. A reference is a name that refers to a value (object).

2018-10-28 14:36:47 Python Data Types

The operation of a Python program hinges on the data it handles. Data values in Python are known as objects; each object, AKA value, has a type.

2018-10-25 15:26:21 Python Lexical Structure

The lexical structure of a programming language is the set of basic rules that govern how you write programs in that language.

2018-10-08 13:55:50 The Python Interpreter

To develop software systems in Python, you write text files that contain Python source code and documentation. You can use any text editor...

2018-10-06 12:58:15 Python Installation

You can install Python in classic (CPython), JVM (Jython), .NET (IronPython), and PyPy versions, on most platforms. With a suitable development system...

2018-10-02 14:14:56 External Variables and Scope

In the program of previous chapter, the variables in main, such as line, longest, etc., are private or local to main. Because they are declared within main, no other function can have direct access to them.

2018-09-29 06:42:51 Character Arrays

The most common type of array in C is the array of characters. To illustrate the use of character arrays and functions to manipulate them, let's write a program that reads a set of text lines and prints the longest. The outline is simple enough...

2018-09-26 13:59:00 Use Functions In C Program

In C, a function is equivalent to a subroutine or function in Fortran, or a procedure or function in Pascal. A function provides a convenient way to encapsulate some computation, which can then be used without worrying about its implementation.

2018-09-22 02:14:35 Use Arrays In C Program

Let is write a program to count the number of occurrences of each digit, of white space characters (blank, tab, newline), and of all other characters. This is artificial, but it permits us to illustrate several aspects of C in one program.

2018-09-21 03:14:20 Character Input and Output

In this chapter, we are going to consider a family of related programs for processing character data. You will find that many programs are just expanded versions of the prototypes that we discuss here.
