When a program, can be a useful tool to track the s of s throughout the execution. A variable is a named storage location that holds a value, which can be a number, a string, or any other data type. An is a combination of variables, values, and operators that produces a result. A is a unit of code that performs a specific action, such as assigning a value to a variable or executing a .
The of a variable is the value assigned to it before any statements are executed. As the program runs, the variable's value may change based on the statements and expressions used. The of a variable is the value it holds at the end of the program or a specific .
Iteration refers to the process of repeating a set of statements multiple times, typically within a loop. The of a loop is a that determines whether the loop should continue running. Boolean expressions evaluate to either true or false, and they often involve s, such as "AND", "OR", and "NOT", or s, such as less than, greater than, and equals.
is the process of combining strings together, often using the "+" operator. During debugging, it is important to identify and fix different types of errors. s occur when the program violates the rules of the programming language, such as a missing semicolon or mismatched parentheses. s, on the other hand, occur when the program runs successfully but produces incorrect results. s are issues that occur during program execution, such as division by zero or accessing an invalid memory location.
Functions are reusable blocks of code that perform a specific task. They can take arguments (input values) and return a value. is a technique where a function calls itself, allowing repetitive tasks to be solved in an elegant and efficient manner. By understanding these keywords and concepts, programmers can effectively analyze and debug their programs.
