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.

50. Create a vector variable vec; it can have any length. Then, write assignment statements that would store the first half of the vector in one variable and the second half in another. Make sure that your assignment statements are general, and work whether vec has an even or odd number of elements (Hint: use a rounding function such as fix).
numMembers is read from input as the size of the vector. Then, numMembers elements are read from input into the vector bikingRoster. Use a loop to access each element in the vector and if the element is less than averageMembers, output the element followed by a space. Ex: If the input is 8 193 102 3 86 38 161 169 153, then the output is: Average: 113 Numbers less than average: 102 3 86 38 1 #include 2 #include 3 using namespace std; 4 5 int main() { 6 7 unsigned int i; 8 double averageMembers; 9 int sumElementData = 0; 10 11 12 13 14 15 16 int numMembers; cin >> numMembers; vector bikingRoster (numMembers); for (i = 0; i > bikingRoster.at(i); sumElement Data + bikingRoster at(i):
numStudents is read from input as the size of the vector. Then, numStudents elements are read from input into the vector id Listings. Use a loop to access each element in the vector and if the element does not equal 8, output the element followed by a newline. Ex: If the input is 48 8 137 51, then the output is: 137 51 TLICHuue \VELLUI 3 using namespace std; 4 5 6 7 8 9 10 11 12 13 14 15 16 int main() { 17 18 19} int numStudents; unsigned int i; cin >> numStudents; vector idListings (numStudents); for (i = 0; i > idListings.at(i); } /* Your code goes here */ return 0;
# 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.
