The price of an item you want to buy is given in dollars and cents. You pay for it in cash by giving the clerk d dollars and c cents. Write specifications for a function that computes the change, if any, that you should receive. Include a statement of purpose, the preconditions and postconditions, and a description of the arguments.
Answer:
Get the actual price of the item and convert it to cents, also get and convert the amount paid to cents.
subtract the actual price of the item from the paid amount ( which is in cents), if the result is greater than zero, covert the result back to dollars and output the result.
Explanation:
The program converts the actual price of the item and the amount paid to cents (where a dollar is equal to 100 cents). The variables are subtracted to get the change to be refunded, the result is converted back to dollars as the actual change to be paid.
Consider the following code:
Token LexicalAnalyzer: : GetToken()
input . GetChar(c);
switch (c) {
case '=':
input . GetChar(c);
if (c = = '=') {
tmp . token_type = EQEQ;
} else if (c = = ' <') {
tmp . token_type = EQLT; }
else if (c = = '>') {
tmp . token_type = EQGT; } else
tmp . token_type = ERROR;
return tmp;
default:
tmp . token_type = ERROR;
return tmp;
1. In the code, input.GetChar() gets the next character from standard input. If GetToken() is called four times, which of the following inputs will return a token whose type is ERROR?
A. ========
A. =<======
B. ===>====
C. =====<==
D. ======<=
2. If GetToken() is called four times on input <==<==, how many times is ERROR returned?
a. 0
b. 1
c. 2
d. 3
Answer:
return tmp;
default:
tmp . token_type = ERROR;
return tmp;
1. In the code, input.GetChar() gets the next character from standard input. If GetToken() is called four times, which of the following inputs will return a token whose type is ERROR?
A. ========
A. =<======
B. ===>====
C. =====<==
D. ======<=
If GetToken() is called four times, ======<= will be the error. The correct option is D.
What is error?Error is a user-performed illegal action that causes the application to operate abnormally.
Programming mistakes frequently go unnoticed until the program is compiled or run. A few of the errors prevent the program from being built or run.
A bug is a mistake, fault, or flaw in any hardware device or computer software. A bug causes an unexpected system behavior or unexpected results.
Each time GetToken() is used, the following occurs: The input is read to read a character. There are two choices: In this instance, we read the following character, which is =.
When invoking GetToken() for the first time, line 2's input getChar(c) will accept the input =, resulting in the storage of "=" in c.
If GetToken() is called four times on input <==<==, the error will return 2 times.
Thus, the correct options are D and C respectively.

Question 2
A Column is 0.5 m diameter and carries a load of 600 Kofker from the controid by
0.1. calculate the extemes of stresses.
Question 3
Answer:
The stress for tensile edge is 1.834 MPa
The stress for compressive edge is -7.945 MPa
Explanation:
Given that,
Force = 600 kN
Diameter = 0.5 m
[tex]y=\dfrac{D}{2}=\dfrac{0.5}{2}=0.25\ m[/tex]
Distance from the centroid to the edge of the column x= 0.1 m
We know that,
Stress for column :
The stress is equal to the sum of banding stress and direct compressive stress.
[tex]\sigma=\sigma_{b}+(-\sigma_{d})[/tex]
The value of binding stress will be positive for tensile and negative for compressive stress.
We need to calculate the stress for tensile edge,
Using formula of stress for tensile edge,
[tex]\sigma=\dfrac{Fxy}{I}-\dfrac{F}{A}[/tex]
Put the value into the formula
[tex]\sigma=\dfrac{600\times1000\times0.1\times0.25}{\pi\times\dfrac{(0.5)^4}{64}}-\dfrac{600\times1000}{\pi\times\dfrac{(0.5)^2}{4}}[/tex]
[tex]\sigma=1.834\ MPa[/tex]
We need to calculate the stress for compressive edge,
Using formula of stress for compressive edge,
[tex]\sigma=-\dfrac{Fxy}{I}-\dfrac{F}{A}[/tex]
Put the value into the formula
[tex]\sigma=-\dfrac{600\times1000\times0.1\times0.25}{\pi\times\dfrac{(0.5)^4}{64}}-\dfrac{600\times1000}{\pi\times\dfrac{(0.5)^2}{4}}[/tex]
[tex]\sigma=-7.945\ MPa[/tex]
Hence, The stress for tensile edge is 1.834 MPa
The stress for compressive edge is -7.945 MPa

11) A single inheritance model means: * A) A class can only have one parent class (superclass) B) A class can only have one child class (subclass) C) A class cannot have a parent class (superclass) D) A class cannot have a child class (subclass) E) A class can have multiple parent classes (superclasses)
Answer:
The correct answer is Option A (A class can only have one parent class (superclass))
Explanation:
The inheritance model is a computer program used in Javascript. This model aimed to make code that has been programmed already still relevant to be used again at any time minimizing errors associated with typing a new code. Inheritance makes the attributes of a particular class valid while still possible to use the attributes of another class.
A child class (subclass) inherits from the parent class (superclass). So, it is a single inheritance once the child class (subclass) inherits from a single parent class (superclass) creating a subclass. A parent class (superclass) is the class that gives its attributes for inheritance.

Edhesive AP Computer Science Coding Activity 2:
Write a method that takes 5 ints as parameters and returns the average value of the 5 ints as a double.
This method must be named average() and it must have 5 int parameters. This method must return a double.
Calling average(1, 5, 7, 4, 10) would return 5.4.
You can call your method in the program's main method so you can test whether it works, but you must remove or comment out the main method before checking your code for a score.
Answer:
The method in C++ is as follows:
double average(int v, int w, int x, int y, int y){
double ave = (v+w+x+y+z)/5.0;
return ave;
}
Explanation:
This defines the average method with 5 parameters
double average(int v, int w, int x, int y, int y){
This calculates the average
double ave = (v+w+x+y+z)/5.0;
This returns the calculated average
return ave;
}
To call the method from the program's main, use:
int main(){
cout<<average(1,5,7,4,10);
return 0;
}

. When attempting to minimize memory usage, the most efficient way to do group processing when using the MEANS procedure is to use: A. the BY statement. B. GROUPBY with the NOTSORTED specification. C. the CLASS statement. D. multiple WHERE statements.
Answer:
A. the BY statement.
Explanation:
The BY statement aids the procedure MEANS to develop the tree for the current BY group only, thereby analyze the stats, and clean the tree prior to the start and development of the next BY group.
However, without the BY statement, procedure MEANS develops its AVL tree for both the whole file and all sector estimates crossings established in CLASS.
Hence, in this case, the correct answer is the BY Statement.
