Question 1

The ____ special character is used with the printf() function in C to indicate a tab.
A)	
B)\0
C)

D)\l

Accepted Answer

The "	" character is used to indicate a tab in the printf() function in C. This character causes the output to move to the next tab stop, which is usually every eight characters.

Question 2

You can use /* and */ instead of ____ symbol(s) for one-line comments in C.
A)#
B)#!
C)**
D)//

Accepted Answer

In C programming language, double forward slashes (//) are used for one-line comments. The other options given are for comments in other languages or for multi-line comments in C.

Question 3

To compile the "syntax.c" program in *nix you enter the gcc -c syntax.c -o syntax.o command.

Accepted Answer

This command compiles the "syntax.c" program and outputs the object file "syntax.o".

Question 4

Software engineering firms don't retain computer programmers who do not document their work because they know that 80% of the cost of software projects is ____.
A)documentation
B)debugging
C)testing
D)maintenance

Accepted Answer

The statement indicates that documentation is important, but it does not state that it comprises 80% of software project costs. Debugging and testing are also important but are not necessarily the majority cost. Maintenance, however, encompasses ongoing work to update and improve software after its initial release, and can often make up a significant portion of project costs. Therefore, the best choice is D.

Question 5

UNIX was first written in assembly language, soon rewritten in ____.
A)Smalltalk
B)Perl
C)Python
D)C

Accepted Answer

UNIX was initially written in assembly language but it was soon rewritten in C language by Dennis Ritchie and Ken Thompson. This was a significant milestone in the history of UNIX as it made it more portable and efficient.

Question 6

The C programming language was developed by ____ at Bell Laboratories in 1972.
A)James Gosling
B)Larry Wall
C)Dennis Ritchie
D)Larry Tesler

Accepted Answer

The C programming language was developed by Dennis Ritchie at Bell Laboratories in 1972.

Question 7

Security professionals often need to examine Web pages and recognize when something looks suspicious.

Accepted Answer

Security professionals need to have the ability to identify potential security risks and be able to recognize suspicious activities on Web pages.

Question 8

____ is the act of performing a task over and over.
A)Branching
B)Looping
C)Testing
D)Remembering

Accepted Answer

Looping is the act of repeating a certain task or block of code multiple times, until a certain condition is met. This is often used in programming to efficiently perform repetitive tasks. Branching refers to the process of selecting between different paths or options in a program based on certain conditions. Testing is the process of evaluating the performance or functionality of a program, typically through a series of automated or manual tests. Remembering refers to the act of recalling information or past experiences, and is not directly related to programming or computer science.

Question 9

The ____ special character is used with the printf() function in C to indicate a new line.
A)	
B)\0
C)

D)\l

Accepted Answer

The 
 special character is called the "newline" character and is used with the printf() function in C to insert a new line after printing output. It moves the cursor to the beginning of the next line of output.

Therefore, the best choice is C.

Question 10

The logical operator in C that is used to compare the equality of two variables is ____.
A)=
B)&&
C)||
D)==

Accepted Answer

The equality operator in C is represented by "==" which checks if the two variables on either side of it are equal or not. Therefore, the correct choice is D.

Question 11

The mathematical operator in C that increments the unary value by 1 is ____.
A)+
B)%
C)++
D)&

Accepted Answer

The ++ operator is a unary operator that increments the value of a variable by 1. It can be used before (prefix) or after (postfix) the variable name.

Question 12

____ takes you from one area of a program (a function) to another area.
A)Branching
B)Looping
C)Testing
D)Dividing

Accepted Answer

Branching statements like if, switch, goto, etc are used to jump from one part of the program to another.

Question 13

The ____ statement in C is used to load libraries that hold the commands and functions used in your program.
A)#include
B)package
C)use
D)#import

Accepted Answer

The #include statement is used in C to load libraries that hold the commands and functions used in your program. It allows you to access previously written code and use it in your program, saving development time and effort.

Question 14

You must always add "//" at the end of comment text in C.

Accepted Answer

The "//" symbol is used to begin a single-line comment in C, but it is not necessary to add it at the end of the comment text. The comment will end automatically at the end of the line.

Question 15

Bugs are worse than syntax errors because a program can run successfully with a bug, but the output might be incorrect or inconsistent.

Accepted Answer

Bugs can cause unexpected behavior or produce incorrect results even if the program runs without any syntax errors. Therefore, bugs can have a greater impact on the functionality and reliability of a program than syntax errors.

Question 16

HTML doesn't use branching, looping, or testing.

Accepted Answer

HTML is a markup language used for structuring content on the web, and it does not include programming constructs like branching, looping, or testing, which are found in programming languages.

Question 17

The logical operator in C that is evaluated as true if both sides of the operator are true is ____.
A)=
B)&&
C)||
D)==

Accepted Answer

The logical operator && is the AND operator. It returns true only when both the conditions on either side of the operator are true.

Question 18

A ____ is a mini program within a main program that carries out a task.
A)function
B)script
C)branch
D)loop

Accepted Answer

A function is a self-contained mini program within a larger program that performs a specific task. It can be called and executed multiple times within the larger program, making the program more modular and easier to manage.

Question 19

In C, ____ show where a block of code begins and ends.
A)braces
B)parenthesis
C)brackets
D)dashes

Accepted Answer

Braces are used to define the beginning and end of a block of code in C.

Question 20

Most programming languages do not have a way to conduct testing of a variable.

Accepted Answer

Most programming languages provide ways to conduct testing of variables using conditionals, such as "if" statements or comparison operators. Some languages even have built-in testing frameworks for more comprehensive testing.
