1.2 Binary files in python

-

 v  Binary files in python: -

  • A binary file is a file that stores data in the form of raw bytes (0s and 1s) instead of plain text.
  • In Python, binary files store data in a non-text format such as images, audio files, videos, serialized objects, and more.
  • Binary files consist of non-human-readable characters and symbols, which require specific programs to access their contents. They are stored as bytes (zeros and ones), but these bytes do not represent ASCII values of characters. Instead, they represent the actual content, such as images, audio, video, compressed files, executable files, etc.
  • Since binary files are not human-readable, opening them in a text editor will display random or unreadable symbols, often referred to as “garbage values”. This happens because the computer interprets the binary content as a sequence of bytes without any text encoding.
  • It is also difficult to remove errors from binary files, as their contents cannot be directly interpreted by humans.
  • Python programs can be used to read and write both text files and binary files efficiently.


1)    Writing Binary files: -

  • Writing Binary Files in Python means storing data as raw bytes instead of plain text.
  • This is useful when you want to save images, audio, video, or any non-text data without corruption.
  • You must provide data in bytes form.
  • We use open( ) method with mode:

                            "wb" → write binary (creates/overwrites file)

                            "ab" → append binary (adds data to end of file)

                            "wb+" → write and read binary

Example: -    


output: -    

2) Reading Binary files: -

  • Reading Binary Files in Python means loading data as raw bytes from a file instead of interpreting it as text. 
  • This is used for images, audio, video, executables, compressed files, or any non-text data.
  • Use open( ) method with mode:

                                                    "rb" → read binary

                                                    "rb+" → read and write binary

Example: -    



output: -

operators in c programming

v Operators: - An operator is a symbol that tells or intimates to the compiler to perform specific calculations or manipulations on one or more operands. Operators are essential for performing computations and making decisions in programs.   a + b is an operation a & b are operands + is an operator   Based on number of operands involved: 1.      Unary operators: - unary operators can be applied on only one operator. Example: -   ++ , -- , - (unary minus) , sizeof , ~ (compliment) , ! (not).   2.      Binary operators: - binary operators can be applied on two operands. Example: -   + , -,   * , / , etc.   3.    Ternary operators: - Ternary operator can be applied on three operands. Example: -   ?: (ternary conditional operator).   C supports several operators, can be classified into following...

2.4 Arrays in c programming

-
Image
  Arrays: - An array is a collection of elements of the same data type stored in contiguous memory locations. It is a derived data type and a homogenous data structure. It is a variable which can store multiple values of the same type under a single variable name, making it easier to manage and manipulate related data. The size of an array is fixed. To access the elements of an array, we use indexes or subscripts accordingly. array index or subscript is used to identify array elements address. Array index or subscript starts with 0 to n-1.   Declaration of an array: - The declaration of an array means telling the compiler to create an array variable and reserving memory for a fixed number of elements of the same data type. Initialization of an array: - Initializing an array means assigning initial values to its elements. Types of arrays: - Arrays are classified based on the number of dimensions they have:             ...

2.1 Control statements in C programming (sequential & conditional)

-
Image
Control statements in C: - C is a structure-orientated programming language; the statements that are used to control the flow of execution of a program are called control structures. The statements provide a specific order to execute the C program. In C programming, we have four types of control structures. Sequential control structures Conditional control structures Iterative control structures Jumping control structures   1) Sequential control structures: - The C program is a collection of instructions or set of statements which are executed sequentially in a user-specific order. No statement is slipped, and no statement is executed more than once.                   Syntax: -                Flow chart: -                Example: - Output: - 1) Conditional control structures: - It is also known as selection, branchi...
