    Program Coding

    Program coding is the process of writing instructions for computers using programming languages.

    Learning Practice

  • 4.1

    What Is Program Coding?

    Program coding is the process of writing instructions for computers using a programming language.

    Learning Practice

  • 4.2

    What Is A Programming Language?

    A programming language is a specialized language used to write instructions for computers, facilitating communication between humans and machines.

    Learning Practice

  • 4.2.1

    Types Of Programming Languages

    This section discusses the two primary types of programming languages: low-level and high-level languages.

    Learning Practice

  • 4.2.1.1

    Low-Level Languages

    Low-level languages are programming languages that are closely aligned with machine code, making them difficult for humans to read and write.

    Learning Practice

  • 4.2.1.2

    High-Level Languages

    High-level languages are designed to be easy for humans to read and write, converting them into machine language using compilers or interpreters.

  • 4.4

    Steps In Writing A Program

    This section outlines the step-by-step process involved in writing a computer program.

    Learning Practice

  • 4.5

    Basic Programming Concepts

    This section introduces fundamental programming concepts, including variables, data types, input/output, operators, and control structures.

    Learning Practice

  • 4.5.1

    Variables

    This section introduces variables as fundamental components in programming, describing their purpose and providing examples.

    Learning Practice

  • 4.5.2

    Data Types

    Data types are classifications of data that determine the values a variable can hold in programming.

    Learning Practice

  • 4.5.3

    Input And Output

    The Input and Output section addresses how computers handle user data and display results through programming.

    Learning Practice

  • 4.5.4

    Operators

    Operators are symbols that perform calculations on values.

    Learning Practice

  • 4.5.5

    Control Structures

    Control structures in programming are key elements that allow decision-making and repetition of tasks in code execution.

    Learning Practice

    Writing A Simple Program (In Python)

    This section introduces simple programming in Python through practical examples, focusing on adding numbers and checking if a number is even or odd.

    Learning Practice

  • 4.6.1

    Example 1: Add Two Numbers

    Learning

  • 4.6.2

    Example 2: Check Even Or Odd

    Errors In Programs

    This section covers the types of errors that can occur in programming, including syntax errors, logic errors, and runtime errors.

    Learning Practice

  • 4.7.1

    Syntax Errors

    Syntax errors are mistakes in the grammar of a programming language that prevent the code from being executed.

    Learning Practice

  • 4.7.2

    Logic Errors

    Logic errors occur when a program runs without crashing but produces incorrect outputs due to flaws in the logic used.

    Learning Practice

  • 4.7.3

    Runtime Errors

    Runtime errors occur during the execution of a program, leading to unexpected termination or incorrect outputs.

    Learning Practice

  • 4.8
