Vectorize the following code. Write statement[s] that accomplish the same thing, eliminating the loop. Assume that there is a vector v that has a negative number in it. Use the following variable v and newv to check your answer. >> v = [4 11 22 5 33 -8 3 99 52] newv = []; i=1; while v(i) >= 0 newv(i) = v(i); i=i+1; end

# phyton A vector contains the grades obtained by students of a class in an assessment, with the following characteristics: Notes are actual values between zero and ten.If the value is equal to -1.0, then this means that the student has missed the assessment.The average approval rate at this University is 6 (six).Write a program that reads two vectors: the note vector described and a vector containing the students' names of the same size. As an output, print the following information in the console in this order: How many students missed the evaluation?How many students have been approved?Among the students present, how many students failed?Among the students present, what was the average grade, with up to two decimal places of accuracy?What's the name of the student who got the highest grade in the class?TipsCreate different counters to find the value of outputs 1 through 4. These counters are different from the loop counter that traverses the vector;Within the while loop, use five…
Integer numInputs is read from input. Given the integer vector hourlyScores with the size of numInputs, write a for loop to output the integers in the second half of hourlyScores in reverse order. Separate the integers with a vertical bar surrounded by spaces ("I Ex: If the input is 8 86 88 97 116 132 146 148 163 then the output is: 163 | 148 | 146 | 132 Note: The vector size is always even. int i; int numInputs; 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23} cin >> numInputs; // Creates a vector of size numInputs and initialize all values to 0 hourlyScores.resize(numInputs); for (i = 0; i > hourlyScores.at(i); } * Your code goes here */ cout << endl; return 0;
Integer numin is read from input. Given the integer vector yearlySalary with the size of numin, write a for loop to initialize the first half of yearlySalary with the remaining integers read from input. Ex: If the input is 6 116 132 134 then the output is: 116 132 134 0 0 0 Note: The vector size is always even. 5 int main() { 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21} vector yearlySalary; unsigned int i; int numIn; cin >> numIn; // Creates a vector of size numIn and initialize all values to 0 yearlySalary.resize(numIn); /* Your code goes here */ for (i = 0; i < yearlySalary.size(); ++i) { cout << yearlySalary.at (i) << " "; } return 0;
Integers are read from input and stored into a vector until 0 is read. If the vector's last element is odd, output the odd elements in the vector. Otherwise, output the even elements in the vector. End each number with a newline. Ex: If the input is -9 12 -6 1 0, the vector's last element is 1. Thus, the output is: -9 1 Note: (x % 2 != 0) returns true if x is odd. int value; int i; bool isodd; 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 } cin >> value; while (value != 0) { } for (i = 0; i > value; Check return 0; 1 Next level 2 X 1: Compare output 3 4 For input -9 12 -6 1 0, the vector elements are -9, 12, -6, and 1. The last element, 1, is odd. The odd elements in the vector, -9 and 1, are output, each on a new line. Not all tests passed. 2 V 3

Write a function that displays an n-by-n matrix using the following header: void printMatrix(int n)Each element is 0 or 1, which is generated randomly. Write a test program that prompts the user to enter n and displays an n-by-n matrix.
Declare a vector of 15 doubles. Using a loop, set all the elements of your vector to 140.041. Write a function named print Vector that returns nothing and takes by constant reference a vector of doubles. The function should print every element of the vector, followed by a newline. Use this function to print out your vector from Assignment 1 above. Using the at() function, change the value of the first two elements to -1.0. Using the push_back () function to add two new elements at the end of the vector with values -10.3 and -20.3. Now use the sort () function on the vector. Using your function from Assignment 2, print the vector. Write a program that takes keyboard input from a user and puts what they type into a string. Print out the number of characters they just typed. Change the first character of the string to 'x'. Now append "<- you typed this!" to the string. Now print the modified string with cout. Caign Declare a vector of 5 strings. In a loop, read from the keyboard into each…

c++ A lottery ticket buyer purchases 10 tickets a week, always playing the same 10 5-digit “lucky” combinations. Write a program that initializes an array or a vector with these numbers and then lets the player enter this week’s winning 5-digit number. The program should perform a linear search through the list of the player’s numbers and report whether or not one of the tickets is a winner this week. Here are the numbers: 13579 26791 26792 33445 55555 62483 77777 79422 85647 93121 If the user enters a number that is not in the array, the program should display a message indicating that the number is invalid.
Integers are read from input and stored into a vector until -1 is read. Output the negative elements in the vector in reverse order. End each number with a newline. Ex: If the input is -8 15 1 -12 -1, then the output is: -12 -8 Note: Negative integers are less than 0. 3 using namespace std; 4 5 int main() { 6 7 8 9 10 11 12 13 14 15 16 17 18 19 } vector dataVect; int value; int i; cin >> value; while (value != -1) { dataVect.push_back(value); cin >> value; /* Your code goes here */ return 0;
