(a) Create a vector "v" containing elements in the order given: "Monday", "Wednesday" and "Friday". (b) Print the vector "v" and print what its type is. (c) Use the R help to learn about the substr function. Use it to obtain the first 3 letters of each element of the vector "v". Save it as a new vector "firstthree" and print "firstthree". (d) Finally, print the second element of the vector "first three"

ASSIGNMENT: Working with Vectors Write a menu-driven program that will allow the user to run any of the following questions. Please put the functions headers in h file and the functions definitions in a .cpp file. 1. Write C++ code for a loop that simultaneously computes both the maximum and minimum element in a given vector. 2. Write a function double scalar_product(vector a, vector b) that computes the scalar product of two vectors. The scalar product of two vectors A[al, a2, a3) and B(bl, b2, b3} is another vector C given by C{c1, c2, c3} where cl = al * b1, c2 = a2 + b2, c3 = a3 + b3. 3. Write a function that computes the alternating sum of all elements in a vector. For example, if alternatingSum() is called with a vector containing 149 16 9 7 4 9 11 then it computes 1-4+9-16+9-7+4-9+11=-2 4. Write a procedure reverse that reverses the sequence of elements in a vector. For example, if reverse is called with a vector containing 1 49 16 9 7 4 9 11 then the vector is changed 11 9 4 7…

Case - II: English narrative is composed of several sentences and where each sentence is comprises of different words including nouns, adjectives, verbs etc. Here we supposed to define and perform few easy operations with the help of C-string. This string contains only lower- and upper-case letters including spaces. No special characters and symbols are entered for ease of this problem. Define a variable of character array (c-string) and get input from user in main() before to prefer the following operations. SO 5. Find the number of characters in this c-string without using built-in function. SO 6. Define a function to find and print the vowels (a,e.i,o,u A,E.L,0,U) exist in this string SO 7. Define a function that print the count of upper-case letters and lower-case letter found in this string. SO 8. Find the number of words in this string based on space-separation simply. [Hint: Consider it as two consecutive words has only one space.] SO 9. Find the number of words in this string…
C++ Create a function append(v1, v2) that adds a copy of all the elements of vector v1 to the end of vector v2. The arguments are vectors of integers. Write a test driver.
3. Use two vectors and make them into one. Use the following vectors:Vector#1 {1, 1, 5, -3, 0}Vector#2 {9,7,2}Return a vector containing 1, 1, 5, -3, 0, 9, 7, 2 (in that order)
You 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. Write a main function that creates an empty vector, calls functions from 2 & 3 and calls your output function before and after each of your calls…
C++.Write a function, named SecondNegative, that takes a const reference to a vector of doubles, it should return an const_iterator to the element in the vector that is the second value that is negative. If no such element exists, have the iterator point to one past the end.
