Explain variables, loops, conditions, functions, etc.
When learning programming, there are some basic concepts that every beginner should understand. These concepts are used in almost every programming language and help you build logical and efficient programs. 1. Variables A variable is used to store data or information in a program. It acts like a container that holds a value which can be changed during program execution. Example: storing numbers, names, or other data. Example (Python): name = "John" age = 20 Here, name and age are variables that store values. 2. Loops Loops are used to repeat a block of code multiple times. Instead of writing the same code again and again, a loop allows the program to run it automatically. Types of loops: For loop – used when the number of repetitions is known. While loop – used when the loop continues until a condition becomes false. Example: for i in range(5): print(i) 3. Conditions (Conditional Statements) Conditions are used to make decisions in a program. They allow the program ...
