Multiple Inheritance Program In C Sharp

The baselist is the inherited class. By default, classes inherit from the System. Object type. A class can inherit and implement multiple interfaces but doesnt. Daily paper.

A component oriented language C is the first component oriented language in the CC family Component concepts are first class. A class is a data structure that may contain data members constants and fields, function members methods, properties, events, indexers, operators, instance. C is an elegant and typesafe objectoriented language that enables developers to build a variety of secure and robust applications that run on the. NET Framework. Free C Video Tutorials for beginners and intermediate programmers. In this article we will see a situation that occurs when two interfaces have methods with the same name and the same parameters and one base class implements these. Operators, Types, and Variables C Station. This lesson introduces C operators, types, and variables. Its goal is to meet the following objectives Understand what a variable is. Familiarization with C built in types. Get an introduction to C operators. Learn how to use Arrays. Variables and TypesVariables are simply storage locations for data.

The interpretation of the data in a variable is controlled through Types. C is a Strongly Typed language. Thus all operations on variables are performed with consideration of what the variables Type is. There are rules that define what operations are legal in order to maintain the integrity of the data you put in a variable. The C simple types consist of the Boolean type and three numeric types Integrals, Floating Point, Decimal, and String. The term Integrals, which is defined in the C Programming Language Specification, refers to the classification of types that include sbyte, byte, short, ushort, int, uint, long, ulong, and char. More details are available in the Integral Types section later in this lesson. The term Floating Point refers to the float and double types, which are discussed, along with the decimal type, in more detail in the Floating Point and Decimal Types section later in this lesson. The string type represents a string of characters and is discussed in The String Type section, later in this lesson. The next section introduces the boolean type. The Boolean Type. Boolean types are declared using the keyword, bool. They have two values true or false. I wonder if youd consider CCLI as something that has many of the advantages of both C and C. Anyhow, for C tutorials with serious threading discussions, I. In other languages, such as C and C, boolean conditions can be satisfied where 0 means false and anything else means true. However, in C the only values that satisfy a boolean condition is true and false, which are official keywords. Listing 2 1 shows one of many ways that boolean types can be used in a program. Listing 2 1. Displaying Boolean Values Boolean. System. publicstaticvoid Main. Content false. Console. Write. LineIt is 0 that C Station provides C programming language content., content. Console. Write. LineThe statement above is not 0., no. Content. In Listing 2 1, the boolean values are written to the console as a part of a sentence. The only legal values for the bool type are either trueor false, as shown by the assignment of true to content and false to no. Content. When run, this program produces the following output It is True that C Station provides C programming language content. The statement above is not False. Integral Types. In C, an integral is a category of types. For anyone confused because the word Integral sounds like a mathematical term, from the perspective of C programming, these are actually defined as Integral types in the C programming language specification. They are whole numbers, either signed or unsigned, and the char type. The char type is a Unicode character, as defined by the Unicode Standard. For more information, visit The Unicode Home Page. Table 2 1. The Size and Range of C Integral Types. Type. Size in bitsRangesbyte. Integral types are well suited for those operations involving whole number calculations. The char type is the exception, representing a single Unicode character. As you can see from the table above, you have a wide range of options to choose from, depending on your requirements. Floating Point and Decimal Types. A C floating point type is either a float or double. They are used any time you need to represent a real number, as defined by IEEE 7. For more information on IEEE 7. IEEE Web Site. Decimal types should be used when representing financial or money values. Table 2 2. The Floating Point and Decimal Types with Size, precision, and Range. Type. Size in bitsprecision. Rangefloat. 32. 7 digits. Floating point types are used when you need to perform operations requiring fractional representations. However, for financial calculations, the decimal type is the best choice because you can avoid rounding errors. The string Type. A string is a sequence of text characters. You typically create a string with a string literal, enclosed in quotes This is an example of a string. Youve seen strings being used in Lesson 1, where we used the Console. Write. Line method to send output to the console. Some characters arent printable, but you still need to use them in strings. Therefore, C has a special syntax where characters can be escaped to represent non printable characters. For example, it is common to use newlines in text, which is represented by the n char. The backslash, represents the escape. When preceded by the escape character, the n is no longer interpreted as an alphabetical character, but now represents a newline. You may be now wondering how you could represent a backslash character in your code. We have to escape that too by typing two backslashes, as in. Table 2 3. C Character Escape Sequences. Escape Sequence. MeaningSingle QuoteDouble QuoteBackslash0. Null, not the same as the C null valuea. Bellb. Backspacefform Feedn. Newliner. Carriage Returnt. Horizontal Tabv. Vertical Tab. Another useful feature of C strings is the verbatim literal, which is a string with a symbol prefix, as in Some string. Verbatim literals make escape sequences translate as normal characters to enhance readability. To appreciate the value of verbatim literals, consider a path statement such as c topdirsubdirsubdirmyapp. As you can see, the backslashes are escaped, causing the string to be less readable. You can improve the string with a verbatim literal, like this c topdirsubdirsubdirmyapp. That is fine, but now you have the problem where quoting text is not as easy. In that case, you would specify double double quotes. For example, the string copy c source file name with spaces. C Operators. Results are computed by building expressions. These expressions are built by combining variables and operators together into statements. The following table describes the allowable operators, their precedence, and associativity. Table 2 4.

Right associativity mean all operations occur from right to left, such as assignment operators where everything to the right is evaluated before the result is placed into the variable on the left. Most operators are either unary or binary. Unary operators form expressions on a single variable, but binary operators form expressions with two variables. Listing 2 2 demonstrates how unary operators are used. Listing 2 2. Unary Operators Unary. System. publicstaticvoid Main. Increment. int pre. Decrement. int post. Increment. int post.
