Chapter 6
All while loops should be converted into for loops
False
Iterative solutions are always better than recursive ones
False
No semi-colon is used after the loop control expression for a do while loop
False
The gcc compiler as used on the guru.itap.purdue.edu server this semester will permit a variable to be declared and initialized in the first expression of a for loop
False
The only way to stop a program caught in an infinite loop is to shut down your terminal software
False
The short-circuit method of evaluating logical expressions does not apply to loop control expressions
False
The update expression of a for loop may only make use of the addition or subtraction operator (includes ++, --, +=, -=, +, -)
False
In an event-controlled loop we know the number of times that the actions found inside the body of the loop will be executed
False (counter-controlled)
A counter controlled loop may execute a constant number of iterations
True
A limited amount of control structures are permissible in the main function to ensure that it is the main function which makes most of the function calls for a program
True
A nested loop is a repetitive process contained inside of another repetitive process
True
A repetitive function is defined as iterative whenever the definition involves only the parameters and not the function itself
True
A repetitive function is defined as recursive whenever the function appears within the definition itself
True
According to the course standards a for loop should only be used with counter-controlled processes.
True
According to the course standards if all three expressions are not needed in a for loop then you should instead make use of a while loop for your pretest looping needs
True
An infinite loop is a logical error
True
An iteration is one execution of all statements found inside of a loop
True
An iterative solution involves the use of a loop
True
An iterative solution is one that is implemented using a looping construct
True
Any statement, even another for loop, can be included in the body of a for loop
True
Control-forcing statements such as break, continue, exit, and the use of multiple return statements in a user-defined function are prohibited by course standards as mechanisms to terminate repetitive processes
True
Every recursive call must either solve part of the problem or reduce the size of the problem
True
Functions that make use of loops can vary widely in efficiency
True
If you think you need to make use of the continue statement then your algorithm may not be well structured
True
In a post-test loop the minimum number of times that the statements found inside of the loop are executed is one
True
In a pretest loop the control expression is evaluated before each iteration, including the first iteration
True
It is not recommended coding technique to update the loop control variable in the body of a for loop rather than making use of the third expression
True
It is possible for the number of times a counter-controlled loop with iterate to depend on the value of a single variable or expression
True
No semi-colon is used after the loop control expression for a while loop
True
One approach to potentially make solving problems that require nested loops easier is to separate each repetitive process into its own function
True
Recursion is a repetitive process in which a function calls itself
True
Recursion should not be used with event-controlled processes as the result may be more function calls than the memory of the computer can accommodate
True
Recursive solutions may involve heavy use of the limited resources of the computer because they involve a potentially large number of function calls
True
Recursive solutions may require heavy use of the limited resources of the computer because they involve a potentially large number of function calls
True
The ability to complement a logical expression is important because programmers often consider what must happen for a loop to terminate rather than the conditions that should keep it going
True
The action that is responsible for changing the result of the loop control expression from true to false is the loop update
True
The condition in a recursive function when which the recursive function calls stop is known as the base case
True
The condition that determines whether iteration is to continue in a loop is known as the loop control expression
True
The contents of a loop have been identified to be repeated in a program
True
The do while loop is commonly used in the process of data validation
True
The do while loop will test the loop control expression after the execution of the statements found inside the body of the loop
True
The efficiency of an algorithm is one measure to determine when one solution should be preferred to another
True
The first expression in a for loop is to initialize the loop control variable
True
The for loop is used when a loop is to be executed a known number of times
True
The for loop is usually for counter-controlled processes
True
The initialization of the loop control variable must take place outside (before) a pretest loop
True
The loop control variable is commonly a part of the loop control expression and the recipient of the loop update action
True
The number of times that the loop control expression is evaluated is one more than the number of iterations in a pretest loop
True
The second expression in a for loop is the loop control expression
True
The third expression in a for loop is the update expression that changes the loop control variable
True
The update to the loop control variable is responsible for terminating the loop because it will eventually result in the loop control expression being false
True
The work done in preparation for a loop is known as loop initialization
True
This for loop will iterate 10 times: for(i = 0; i < 10; i++)
True
This for loop will iterate 5 times: for(i = 12345; i != 0; i /= 10)
True
This for loop will iterate 6 times: for(i = 1; i <= 32; i * 2)
True
You can make use of x++, ++x, x += 1, and x = x + 1 interchangeably as the update (third) expression of a for loop to increment the loop control variable
True
