Question 1

An advantage of structured programming is that it works well with the concept of modular programming.

Accepted Answer

Structured programming promotes the use of small, manageable blocks of code (procedures, functions, modules) which aligns well with the concept of modular programming, where software is divided into separate modules that can be developed and tested independently.

Question 2

An advantage of structured programming is that structures can be pulled out of programs and inserted into other programs without adversely affecting the flow of the surrounding code.

Accepted Answer

Structured programming promotes modularity, allowing code to be reused and integrated into other programs without disrupting their flow.

Question 3

Structured programming is most often characterized by the GOTO statement, common in early line-number BASIC programs.

Accepted Answer

Structured programming is characterized by the use of loops, conditionals, and subroutines instead of the GOTO statement, promoting clearer and more maintainable code.

Question 4

Structures are easy to find and change: They have one entry point and one exit point-a clear beginning and end.

Accepted Answer

Structures have a clear beginning and end, making them easy to find and change.

Question 5

Procedural programming is widely accepted as the most efficient method of program development, resulting in faster development, reusable code, easier maintenance, and fewer errors.

Accepted Answer

Procedural programming has its advantages, such as simplicity and ease of understanding for small programs, but it is not universally accepted as the most efficient method of program development. Object-oriented programming (OOP) and other paradigms are often preferred for larger, more complex applications due to better code reuse, maintainability, and scalability.

Question 6

When code is not written by using modules, it is difficult to know what effect changing a line of code will have on surrounding statements.

Accepted Answer

Without modular programming, code is often tightly coupled and lacks clear boundaries, making it hard to predict how changes in one part will affect the rest of the program.

Question 7

Structured programming is commonly called "spaghetti code."

Accepted Answer

Structured programming is a programming paradigm aimed at improving the clarity, quality, and development time of a computer program by making extensive use of subroutines, block structures, and loops, in contrast to "spaghetti code," which is a pejorative term for unstructured and difficult to maintain code.

Question 8

The "stored programming" concept developed by John von Neumann states that any program can be written by using only sequence, selection, and repetition structures.

Accepted Answer

The "stored programming" concept developed by John von Neumann states that any program can be written by using only sequence, selection, and repetition structures.

Question 9

The following is an example of a nonstructured program: 100 PRINT "Enter a number (or 0 to quit): " 110 INPUT N 120 WHILE N <> 0 120 $\quad $ IF N < 0 THEN PRINT "Your number is negative." 130 $\quad $ IF N > 0 THEN PRINT "Your number is positive." 140 $\quad $ PRINT "Enter a number (or 0 to quit): " 150 $\quad $INPUT N 160 END WHILE 200 PRINT "Thank you!"

Accepted Answer

The given example uses structured programming constructs such as WHILE loops and IF statements, which are indicative of structured programming, not nonstructured programming.

Question 10

Statements in a sequence structure are performed without any conditions.

Accepted Answer

In a sequence structure, statements are executed in order, one after another, without any conditions dictating the flow of execution.

Question 11

On a flowchart, a variable declaration is considered a process, so it is placed in a parallelogram.

Accepted Answer

In a flowchart, a process, such as calculations or variable assignments, is represented by a rectangle, not a parallelogram. A parallelogram is used to represent input or output operations.

Question 12

On a flowchart, symbols are connected by flowlines that indicate the order of processing.

Accepted Answer

Flowlines on a flowchart indeed indicate the sequence in which processes or operations are carried out, connecting symbols to show the flow of control.

Question 13

Flowcharts can be drawn to move from top to bottom or from left to right, whichever fits the page better.

Accepted Answer

Flowcharts are flexible in their layout and can be oriented either vertically (top to bottom) or horizontally (left to right) to best utilize the available space and improve readability.

Question 14

Modules (which include methods and functions) are sections of programming code, and as a result, they are made up of sequence, selection, and repetition structures, just as other program code is.

Accepted Answer

Modules, like any other sections of programming code, are built using fundamental programming structures such as sequence (executing statements one after another), selection (making decisions using if-else statements), and repetition (using loops like for or while) to perform their tasks.

Question 15

The computer always processes comments.

Accepted Answer

Comments are ignored by the computer during the processing of code; they are meant for human readers to understand the code better.

Question 16

Comments are included in programs to aid the programmer.

Accepted Answer

Comments are used in programming to provide explanations or annotations within the code, which help programmers understand the functionality, purpose, or specific details of the code, making it easier to read and maintain.

Question 17

Every time a module is called, the computer suspends execution of the main program, runs the module, and then returns to the next statement in the main program.

Accepted Answer

This describes the basic behavior of function or module calls in programming. When a module (or function) is called, the current point of execution in the main program is paused, control is transferred to the called module, and upon completion, execution resumes at the point immediately following the call in the main program.

Question 18

Modules are represented by rectangles with stripes.

Accepted Answer

Modules are represented by rectangles with stripes in UML class diagrams.

Question 19

Modular programming helps keep your main program uncluttered and easy to understand.

Accepted Answer

Modular programming involves dividing a program into separate sub-programs or modules, each of which handles a specific part of the program's functionality. This approach helps keep the main program simpler and more organized, making it easier to understand and maintain.

Question 20

Right-brained people tend to favor pseudocode as a method of developing algorithms for programs

Accepted Answer

The concept of "right-brained" or "left-brained" people is an oversimplification and does not accurately reflect how brain hemispheres work or influence preferences such as the use of pseudocode in programming.
