Programming Fundamentals

In many programming contexts, DIV (or integer division) performs division and returns only the whole number quotient, discarding the remainder.

The MOD (modulo) operator returns the remainder left over after a division operation is performed.

The value True is a logical value, which is represented by the Boolean data type in programming.

-23 is a whole number, which is classified as an Integer in programming.

A single symbol like '%' is classified as a Character data type, whereas a sequence of symbols would be a String.

Numbers that contain decimal points are referred to as Real or Float data types in programming.

In procedural programming, a function is designed to return a value to the caller, while a procedure performs a task without returning a value.

Subprograms are used to reduce code complexity and improve maintainability; they do not increase the amount of code required, but rather help organize it.

Sequencing is the basic construct where instructions are executed one after another in the order they appear.

Iteration, or looping, allows a block of code to be executed repeatedly as long as a specific condition is met.

If is a selection construct used for conditional branching, not an iteration construct.

Option A uses the correct assignment operator (=) and square brackets to define a list or array of strings.

Option D correctly compares the integer 16 and the string "blue" using the logical AND operator.

The for loop is a standard construct for iteration in programming.

Option B is the correct syntax for comparing an integer variable to a numeric value.

The if statement is the fundamental construct for selection in programming.

Procedural programming is built on sequence, selection, and iteration. Objects are the core of Object-Oriented Programming, not procedural programming.

An array is a data structure that can store multiple values under a single name. Variables and constants typically hold a single value at a time.

A constant is a value that does not change during program execution, not a data type. String, Character, and Boolean are standard data types used to categorize data.

In Python, the input function is used to capture user input, and the assignment operator (=) stores that value into a variable. Option B correctly uses the function with a prompt string.

A constant is a named memory location whose value is fixed and cannot be altered once the program is running. Variables, by contrast, are designed to have their values changed.

In Python 3, print is a function, so it requires parentheses to enclose the arguments. Option C correctly uses parentheses and quotes for the string.

A variable is a named memory location used to store data that can be modified or updated during the program's execution. This distinguishes it from a constant.
