- What is programming?
- Programming is the process of designing and building an executable computer program to accomplish a specific task or solve a problem.
- What are the basic components of a computer program?
- Variables, control structures (like loops and conditionals), functions/methods, and data structures are some of the basic components of a computer program.
- What is a variable?
- A variable is a named storage location in a computer’s memory that can hold different values during the execution of a program.
- What are the main programming paradigms?
- The main programming paradigms include procedural, object-oriented, functional, and declarative programming.
- What is object-oriented programming (OOP)?
- OOP is a programming paradigm based on the concept of “objects,” which can contain data in the form of fields (attributes or properties) and code in the form of procedures (methods or functions).
- What is the difference between a class and an object?
- A class is a blueprint or template for creating objects, whereas an object is an instance of a class.
- What is a method?
- A method is a function that is associated with a class or an object in object-oriented programming.
- What is inheritance in OOP?
- Inheritance is a mechanism in object-oriented programming that allows a class to inherit properties and methods from another class.
- What is polymorphism?
- Polymorphism is the ability of different objects to respond to the same message or method call in different ways.
- What is encapsulation?
- Encapsulation is the bundling of data and methods that operate on that data into a single unit, typically a class in object-oriented programming.
- What is the difference between compile-time and runtime?
- Compile-time refers to the time when the source code is converted into machine code by the compiler, while runtime refers to the time when the program is executed.
- What is a compiler?
- A compiler is a program that translates source code written in a high-level programming language into machine code that can be executed by a computer.
- What is an interpreter?
- An interpreter is a program that reads and executes code line by line, translating each line into machine code as it runs.
- What is the difference between a compiler and an interpreter?
- A compiler translates the entire source code into machine code before execution, while an interpreter translates and executes the source code line by line.
- What is a data type?
- A data type is a classification of data that specifies the type of values that a variable can hold and the operations that can be performed on those values.
- What are the basic data types in most programming languages?
- Basic data types include integers, floating-point numbers, characters, and boolean values.
- What is a loop?
- A loop is a control structure that repeats a block of code until a certain condition is met.
- What are the main types of loops?
- The main types of loops are the for loop, the while loop, and the do-while loop.
- What is a conditional statement?
- A conditional statement is a control structure that executes different code blocks depending on whether a specified condition evaluates to true or false.
- What are the main types of conditional statements?
- The main types of conditional statements are the if statement, the else statement, the else-if statement (in languages that support it), and the switch statement.
- What is recursion?
- Recursion is a programming technique in which a function calls itself in order to solve a problem.
- What is a function?
- A function is a block of code that performs a specific task and can be called from other parts of the program.
- What is a parameter?
- A parameter is a variable that is passed to a function when it is called, allowing the function to operate on different values.
- What is a return value?
- A return value is the value that a function returns to the caller after it has finished executing.
- What is debugging?
- Debugging is the process of identifying and fixing errors, or bugs, in a computer program.
- What is an algorithm?
- An algorithm is a step-by-step procedure for solving a problem or accomplishing a task.
- What is a data structure?
- A data structure is a way of organizing and storing data in a computer’s memory so that it can be accessed and manipulated efficiently.
- What are some common data structures?
- Common data structures include arrays, linked lists, stacks, queues, trees, and graphs.
- What is an array?
- An array is a collection of elements of the same data type that are stored in contiguous memory locations and can be accessed using an index.
- What is a linked list?
- A linked list is a data structure consisting of a sequence of elements, where each element points to the next element in the sequence.
- What is a stack?
- A stack is a data structure that follows the Last In, First Out (LIFO) principle, where elements are inserted and removed from the same end, called the top.
- What is a queue?
- A queue is a data structure that follows the First In, First Out (FIFO) principle, where elements are inserted at the rear and removed from the front.
- What is a tree?
- A tree is a hierarchical data structure consisting of nodes connected by edges, with a single node called the root and no cycles.
- What is a graph?
- A graph is a non-linear data structure consisting of nodes connected by edges, where edges may have a direction (directed graph) or not (undirected graph).
- What is dynamic programming?
- Dynamic programming is a method for solving complex problems by breaking them down into simpler subproblems and solving each subproblem only once, storing the solutions in a table to avoid redundant computations.
- What is Big O notation?
- Big O notation is a mathematical notation used to describe the asymptotic behavior of an algorithm in terms of its worst-case or average-case time complexity or space complexity.
- What is time complexity?
- Time complexity is a measure of the amount of time taken by an algorithm to solve a problem as a function of the size of the input.
- What is space complexity?
- Space complexity is a measure of the amount of memory used by an algorithm to solve a problem as a function of the size of the input.
- What is sorting?
- Sorting is the process of arranging the elements of a list in a specific order, such as numerical or lexicographical order.
- What are some common sorting algorithms?
- Common sorting algorithms include bubble sort, selection sort, insertion sort, merge sort, quick sort, and heap sort.
- What is searching?
- Searching is the
- What are some common searching algorithms?
- Common searching algorithms include linear search, binary search (for sorted arrays), and hash table-based search (for associative arrays).
- What is a hash table?
- A hash table is a data structure that stores key-value pairs and allows for fast retrieval of values based on their keys.
- What is a pointer?
- A pointer is a variable that stores the memory address of another variable.
- What is memory management?
- Memory management is the process of allocating and deallocating memory in a computer’s memory system.
- What is garbage collection?
- Garbage collection is an automatic memory management process that reclaims memory occupied by objects that are no longer in use by the program.
- What is concurrency?
- Concurrency is the ability of a program to execute multiple tasks simultaneously.
- What is a thread?
- A thread is the smallest unit of execution within a process, and multiple threads can run concurrently within the same process.
- What is a deadlock?
- A deadlock is a situation in which two or more processes or threads are unable to proceed because each is waiting for the other to release a resource.
- What is a race condition?
- A race condition is a situation in which the behavior of a program depends on the relative timing of multiple threads or processes.
