Question

Transcribed Image Text:Integer inputSize is read from input. Then, integers and strings are read and stored into integer vector quantityList and string
vector foodList, respectively. Lastly, integer quantityAsked is read from input. Find quantityAsked in quantityList and output the
following:
• "The quantity"
• the value of quantityAsked
• 'is matched with food'
• the element in foodList at the index of quantityAsked in quantityList
and is at index"
• the index of quantityAsked in quantityList
End with a newline.
Ex: If the input is:
4
44 lettuce 48 chicken 59 guava 40 pineapple
48
Then the output is:
The quantity 48 is matched with food chicken and is at index 1
Note: quantityAsked is an element in quantityList.

Expert Solution

arrow_forward
Step 1
Algorithm:
1. Start
2. Declare an integer variable inputSize, an integer variable quantityAsked, and an unsigned integer variable i.
3. Read the size of the input and store it in input size.
4. Declare a vector quantity list of size inputs.
5. Declare a vector food list of size inputs.
6. For i = 0 to inputSize - 1, read in the quantity and food name and store it in quantityList and foodList respectively.
7. Read in the quantity asked and store it in quantityAsked.
8. For i = 0 to input size - 1, check if the quantity in the quantity list at index i is equal to the quantity asked.
9. If yes, print out the food at index i in foodList, index, and break the loop.
10. End.

Adult= £25 and Child = £15 Thursday. Adult = £40 and child = £20 I have made a vector to store this information Vectorticket ={“Monday”, “Thursday”}; Vectoradult = {25, 40}; Vectorchildren ={15, 20}; Thr format of the adult and children vectors is in the order such that the first elements in those vectors correspond with the first element in the ticket vector Now what am struggling with, is i want the program to calculate the total cost of the tickets in correspondant with The user’s inputs which will be the quantity of how many tickets the user bought respectively (adult and children) So something like Monday 1 2 So 1 will be quantity of adult ticket and 2 will quantity of children ticket and the total costs of both added togetherarrow_forward
- Write a findSpelling Function -PHP Write a function findSpellings($word, $allWords) that takes a string and an array of dictionary words as parameters. The function should return an array of possible spellings for a misspelled $word. One way to approach this is to use the soundex() Words that have the same soundex are spelled similarly. Return an array of words from $allWords that match the soundex for $word. I have most of the code. How do I append the $sound to the $mathcing array?arrow_forwardhappy Eidarrow_forwardYou may use the vector and iostream libraries. You are allowed to use three built-in vector member functions (and no others) but you may not have to use them all. The member functions you are allowed to use are size(), at(), and push_back() Write a function that outputs a vector of doubles with each number in the vector separated by a space then a newline after the entire vector is output. The whole vector output should be preceded by a single line saying "Current Vector Contents:". Write a function that takes a vector a doubles and reverses the order of all the elements of the vector. Write a function that fills a vector of doubles with positive numbers using the standard input stream cin, terminate the input when the user enters any negative number. A single output prompt should precede the initial input stating directions for user.

- ] ] get_nhbr In the cell below, you are to write a function called "get_nhbr(Ist, graph)" that takes in two inputs: a list of vertices and a graph. The function is to return a list that contains the neighborhood of the vertices in 'Ist' (remember that this means you are finding the union of the individual vertices' neighborhoods). + Code + Markdown After compiling the above cell, you should be able to compile the following cell and obtain the desired outputs. print (get_nhbr(["A", "D"], {"A" : ["B"], "B" : ["A", "D", "E"], "C" : ["E"], "D":["B"], "E":["B","C","F"], "F":["E"]}), get_nhbr(["B", "C", "F"], {"A" : ["B"], "B" : ["A", "D", "E"], "C" : ["E"], "D":["B"], "E":["B","C","F"], "F":["E"]})) This should return ["B"] ["A", "D", "E"] Python Pythonarrow_forwardWrite a statement that declares a dynamic array of 5 strings and lets a pointer variable p to point to that array A/arrow_forwardvoid getVectorSize(int& size); void readData(vector<Highscore>& scores); void sortData(vector<Highscore>& scores); vector<Highscore>::iterator findLocationOfLargest( const vector<Highscore>::iterator startingLocation, const vector<Highscore>::iterator endingLocation); void displayData(const vector<Highscore>& scores); The size parameter from the given code won't be needed now, since a vector knows its own size. Notice that the findLocationOfLargest() function does not need the vector itself as a parameter, since you can access the vector using the provided iterator parameters. The name field in the struct must still be a c-string The focus of this assignment is to use iterators. You must use iterators wherever possible to access the vector. As a result, you must not use square brackets, the push_back() function, the at() function, etc. Also, the word "index" shouldn't appear in your code anywhere.
