Why does a variable need a data type?

Here are the answers to the questions: 26) Why does a variable need a data type? A) You know what type of data goes in the variable A data type tells the programmer and the computer what kind of values a variable can hold (e.g., whole numbers, decimal numbers, text) and what operations can be performed on it. 27) Given the statement numeric minutes; What is minutes? C) variable name In this declaration, numeric is the data type, and minutes is the identifier or name given to the variable. 28) How does the compiler handle the statement b=a? A) The assignment operator assigns the value of a into b. The = symbol is the assignment operator. It takes the value from the right-hand side (a) and stores it into the variable on the left-hand side (b). 29) What is one of the most important aspects of software development that is often neglected? A) Testing Testing is crucial for identifying bugs, ensuring the software meets requirements, and verifying its quality, but it is frequently underestimated or rushed in development cycles. 30) Which of the following is true of pseudocode? C) It helps the programmer "think out" a program Pseudocode is a planning tool that allows programmers to outline the logic of an algorithm in a human-readable format before writing actual code. 31) switch is an example of a B) statement A switch is a control flow statement that allows a program to execute different blocks of code based on the value of an expression. 32) Syntax involves rules that must be followed when writing a program A) True Syntax refers to the set of rules that define the combinations of symbols that are considered to be correctly structured statements or expressions in a particular programming language. 33) What is a variable? D) A memory location reserved by the program A variable is a named storage location in a computer's memory that holds a value, which can change during program execution. 34) The purpose of the compiler is to convert object code into source code. B) False The purpose of a compiler is to convert source code (human-readable code) into object code (machine-readable code). 35) What is the purpose of placing comments in your source code? C) You and others don't know what is (This option is incomplete, but based on common knowledge, the full intent is likely "You and others can understand what the code does.") Comments are explanatory notes within the source code that are ignored by the compiler but help programmers understand the code's logic, purpose, and functionality.
