infinite (endless)

A loop with an incorrect condition or increment will allow program control to get stuck in the loop forever. Such a loop is called an _____________ loop.

3, 2, 1, 4

Arrange the following lines in order to solve the following problem: Write a C++ code snippet to create a char variable. Print it without initializing the variable. Then, initialize the variable with the value 'c' and print it again. 1. variable = 'c' 2. cout << "Before initialization: " << variable << endl; 3. char variable; 4. cout << "After initialization: " << variable << endl;

2, 4, 1, 5, 3

Arrange the following lines to form a C++ code snippet to declare an integer constant with the value 12. Then declare another integer variable. Prompt the user to enter a value and read in the value from the user. The print the sum of the 2 values 1. int value; 2. const int TWELVE = 12; 3. cout << "The sum is: " << TWELVE < + value << endl; 4. cout << "Enter a value: "; 5. cin >> value;

2, 4, 1, 3

Assignment is a process with multiple steps. The following lines are the individual parts of the C++ line answer = total - deductions. Arrange them in the order of processing. 1. the result of the subtraction is carried back to the program from the processor. 2. the values of "total" and "deductions" are taken to the processor from memory 3. The result of the subtraction is assigned as the value to the variable "answer" 4. the subtraction is done in the processor

main

Each c++ executable that is run should have exactly one ________ function, where execution begins

How many times does this loop run? int i = 20; while (i < 60) {cout<<i<<endl;i+=4;}

10 15 19

Let us assumer we have a global variable called 'x' with the value 19. What is the output of this code snippets?

identifier, literal, comment, directive, keyword, operator

Match the items to the C++ lexical element: value 5.769 // something here #include <iomanip> return <<

3, 1, 4, 2

Order the following categories of operators in decreasing order of precedence (highest to lowest) 1. relational operator 2. assignment operator 3. arithmetic operator 4. logical operator

a (the variable to store the result of the operation)

The conditional operator takes 3 operands. Which of the following is NOT an operand of the conditional operator? aThe variable to store the result of the operation bThe condition cThe if block d The else block

cout<<static_cast<double>(val1)/val2;

The following lines of code will print 3 as the result. int val1 = 30, val2 = 8; cout<< val1/val2; Edit the last line to print the "Correct" answer 3.75 instead. Please type the full line in without spaces.

b (binary)

The insertion operator << is a unary b binary c ternary d depends on the number of items bring printed

c (linking)

The program is translated into an executable and available for running after which of the following phases? a Preprocessing b Compiling c Linking d Execution

Software Development

This requires deeper knowledge of Computer Science including theory and hardware

Application Development

This requires domain knowledge as well as a general understanding of Computer Science

What is printed by this code snippet?

What is the arity of the >> (extraction) operator used in a cin statement? a 1 - The variable to be read in b 2 - the incoming stream from the keyboard and the variable to be read in c 3 - cin, the variable, and the value coming in d Indeterminate - a cin statement can read in multiple values

c (char)

What is the best data type for the value '3'? a int b bool c char d double
