Given the declaration: char a[] = "Hello"; char *p = a, *q; what operations are valid syntactically? Select all that apply. Group of answer choices q = &&a[0]; q = &&a; *q = *(&a[0]); q = &(*p);

Answers

Answer 1

Answer:

The valid operations are:

*q = *(&a[0]);  and q = &(*p);

Explanation:

Given

The above declarations

Required

The valid operations

*q = *(&a[0]);  and q = &(*p); are valid assignment operations.

However, q = &&a[0]; q = &&a; are invalid because:

The assignment operations intend to implicitly cast the char array a to pointer q. C++ does not allow such operation.

Hence, *q = *(&a[0]);  and q = &(*p); are valid

Another way to know the valid operations is to run the program and look out for the syntax errors thrown by the C++ compiler

if a+1/a=3 find the valie of a^2+1/a^2​

Answers

Answer:

a² + 1/a² = 7

Explanation:

a + 1/a = 3 ; obtain the value of a² + 1/a²

Taking a + 1/a = 3

Squaring both sides ;

(a + 1/a)² = 3²

(a + 1/a)(a + 1/a) = a² + a/a + a/a + 1/a² = 3²

(a + 1/a)(a + 1/a) = a² + 1 + 1 + 1/a² = 9

a² + 2 + 1/a² = 9

a² + 1/a² = 9 - 2

a² + 1/a² = 7

Hence,

a² + 1/a² = 7

Display all of the scores entered and the total score at the end. Using the code below, put the code in the proper order Sample output: Welcome to the Test Score Program Add score: 88.45 Do you want to continue

Answers

Answer and Explanation:

Using Javascript:

function AddScores(){

Window.alert("Welcome to the Test Score Program");

var ScoreList= new Array();

ScoreList.push(Prompt("Add Score"));

var WhatNext= Confirm("do you want to continue?");

If(WhatNext===true) {

do{

ScoreList.push(Prompt("Add Score"));

}

While(

Confirm("do you want to continue?")===true;);

}

Alert(ScoreList);

Alert(ScoreList.reduce(function(a,b){return a +b};,0);)

}

AddScores();

From the above code in javascript programming language, we have created a list ScoreList and added elements to it using push method of the array object and a do...while loop that checks the condition and then adds the user's input to the array. We then alerted the array to the screen and then summed up the array elements and also alerted to the screen.

as the amount to be charged for each mile per hour over the speed limit.
The court cost should be $50.00

Answers

Answer:

Following are the code to the given question:

def speedlimit():#defining a method speedlimit

a= int(input("Enter the offender's speed in mph: "))#defining a variable for input value

lim = int(input("Enter the speed limit in mph: "))#defining a variable for input value

n = int(input("The number of previous tickets that person has received: "))#defining a variable for input value

if (lim >= 20) and (lim < 70):#defining if block to check speed is between 20 to 70

if a > lim:#use if to check lim value greater than a

print("Driver was going", a-lim, "mph over the limit.")#print calculated value with message

print("The cost of the speeding ticket $",10*(a-lim))#print calculated value with message

else:

print( "Driver was going at a legal speed.")#print message

else:

print('Invalid speed limit.')#print calculated value with message

print("Court cost $",(50 + n*20))#print calculated value with message

speedlimit()

Output:

Please find the attached file.

Explanation:

In this code, a method "speedlimit" is declared that defines three variables that are "a, lim, and n" in which we input value from the user-end.

Inside the method, a nested conditional statement is used that checks the speed value is between 20 to 70 if it is true it will go to the next condition in which it checks lim value greater than a. It will use a print message that will print the calculated value with the message.

Explanation:  Last summer, my family and I took a trip to Jamaica. My favorite part of the trip was when we went to a place called the Luminous Lagoon. We ate dinner and waited for the sun to go down. Then we boarded a boat and went out into the lagoon. That’s when the magic started.

At first we could not see very much in the darkness except for the stars in the sky. After a few minutes, however, I noticed some fish swimming in the water. They didn’t look like ordinary fish. These fish were glowing! Our guide explained that the glow came from tiny creatures in the water called dinoflagellates. These little animals are not visible to us, but their bodies produce light using something called bioluminescence, just like fireflies. There are so many of these creatures in Luminous Lagoon that the water around them seems to glow.

After our guide explained these facts to us, he told us to put our hands in the water. I was not sure if it would work, but I tried it. When I did, my hand looked like it belonged to a superhero! It was glowing bright blue. I hope someday I get to return to the Luminous Lagoon. The lights in the water were much more entertaining than the ones in the sky.

Problem:

Answers

Answer:

The function is as follows:

def  kelvin_to_celsius(value_kelvin):

   value_celsius = 0.0

   value_celsius = value_kelvin - 273.15

   return value_celsius

Explanation:

This defines the function

def  kelvin_to_celsius(value_kelvin):

This initializes value_celsius to 0

   value_celsius = 0.0

This calculates value_celsius

   value_celsius = value_kelvin - 273.15

This returns the calculated value_celsius

   return value_celsius
