Loops are used to execute a block of code repeatedly, often with different variables, until a specified condition is met.
Variables are symbolic names associated with values that can change during program execution.
An algorithm is a well-defined procedure or formula for solving a problem.
A while loop checks the condition before executing the loop body, ensuring that the condition is met before proceeding.
Conditional statements allow the program to execute different code sections based on whether a condition is true or false.
A function is a block of organized, reusable code designed to perform a single, related action.
The Boolean data type represents values of true or false in programming.
Syntax refers to the set of rules that define the structure and arrangements of symbols, words, and expressions in a programming language.
An if statement is used to execute code only if a specified condition evaluates to true.
Debugging is the process of finding and resolving errors or bugs in the code to ensure the program works correctly.
A string is a sequence of characters used to represent text in programming.
An array is a data structure consisting of a collection of elements, each identified by an index or a key.
