- Every data structure that we use in computer science has its weaknesses and strengthsHaving a full understanding of each will help make us better programmers!For this experiment, let's work with STL vectors and STL dequesFull requirements descriptions are found in the source code file Part 1Work with inserting elements at the front of a vector and a deque (30%) Part 2Work with inserting elements at the back of a vector and a deque (30%) Part 3Work with inserting elements in the middle, and removing elements from, a vector and a deque (40%) Please make sure to put your code specifically where it is asked for, and no where elseDo not modify any of the code you already see in the template file This C++ source code file is required to complete this problemWrite a function that removes duplicates from a vector. For example, if remove duplicates is called with a vector containing 1 4 9 16 9 7 4 9 11 (use these numbers) then the vector is changed to 1 4 9 16 7 11Write a C++ program that does the following steps: stores 16 integer random numbers in a vector container V. The random numbers range in value (0 – 199). One can generate such numbers by invoking the random number generation function, rand( ) and using the % (mod)operator Prior to using the rand( ) function, initialize the random number generator with the srand(17) Print the entire vector after filling the vector container V Create a function Total(vector iterator, Size) that returns the total sum of the vector V Count the number of values exceeding 85 and print the result Remove all numbers from the vector V that are divisible by 3 Print the entire modified reduced vector after the removal step Create a set S(descending order) from the modified vector V Print Set S Remove the first number in S that is divisible by 4 Print modified Set S
- Write the definition for a class named Vector2D that stores information about a two-dimensional vector. The class should have functions to get and set the x and y components, where x and y are integers.Next, overload the * operator so that it returns the dot product of two vectors. The dot product of two-dimensional vectors A and B is equal to(Ax * Bx) + (Ay * By).Finally, write a main subroutine that tests the * operation.Write a function named addStars that accepts as a parameter a reference to a vector of strings, and modifies the vector by placing a "*" element between elements, as well as at the start and end of the vector. For example, if the vector v contains {"the", "quick", "brown", "fox"}, the call of addStars(v); should modify it to store {"*", "the", "*", "quick", "*", "brown", "*", "fox", "*"}.In c++ iv read from a text file containing integers Example 11,1 22, 3 12, 4 And stored each colum in a vector vectorx and vectory How can i make a class for x integers and class for y integers I will use this classes to compare these x and y integers
- Create a function append(v, a, n) that adds to the end of vector v a copy of all the elements of array a. For example, if v contains 1,2, 3, and a contains 4, 5, 6, then v will end up containing 1, 2, 3, 4, 5,6. The argument n is the size of the array. The argument v is a vector ofintegers and a is an array of integers. Write a test driver.Which shows valid accesses for an array a and vector v, each with 10 elements? In other words, this question is asking what is the proper syntax for accessing the array and vector. a. array: a[7] vector: v.at(5) b. array: a.at(5) vector: v[9] c. array: a.at(5) vector: v[5] d. array: a[1] vector v.at[4] Coding is in C++.Write a program in C++ which asks the user to keep entering positive integers or -1 to quit. Then print how many values they entered, the value of each element they entered, and the average of the values (rounded to two decimal places). Requirements The code must use a vector to store the user data. Do not use a counter variable while asking the user for input. Instead, use the vector method to "push" values onto the vector, then later use the vector size method to determine how many values were pushed. The loop to show the values and calculate the average must use a "for each" loop iterator.
- Define a function named GetWordFrequency that takes a vector of strings and a search word as parameters. Function GetWordFrequency() then returns the number of occurrences of the search word in the vector parameter (case insensitive). Then, write a main program that reads a list of words into a vector, calls function GetWordFrequency() repeatedly, and outputs the words in the vector with their frequencies. The input begins with an integer indicating the number of words that follow. Ex: If the input is: 5 hey Hi Mark hi mark the output is: hey 1 Hi 2 Mark 2 hi 2 mark 2 Hint: Use tolower() to set the first letter of each word to lowercase before comparing. The program must define and use the following function:int GetWordFrequency(vector<string> wordsList, string currWord) write code in c++Define a function named GetWordFrequency that takes a vector of strings and a search word as parameters. Function GetWordFrequency() then returns the number of occurrences of the search word in the vector parameter (case insensitive).

The program must define and use the following function:int GetWordFrequency(vector<string> wordsList, string currWord)Write a complete C++ program in one file here which reads a list of names from a file called “roster.txt” (names may contain spaces, one name per line) and stores them in a vector of strings. The file may have any number of names in it (your code cannot be dependent on a specific size). After having read in the names, print out the number of names in the vector using the vector size and print the names themselves from the vector. Your program must use a function to read from the file into the vector and another function to print the names from the vector. Upload as names.cpp – you do NOT need to upload roster.txt.
