Question
Write a C++ Program:
Implement a sort function using a vector.
Ask the user to enter numbers to be sorted. Add them to the vector. The user will signal the end of input by
giving you a negative number.
Then, sort the vector. Because this is a vector, you don’t need to pass the number of entries
in the vector.
Then, print out the vector in order.
Remember the following things about
a) You declare a vector v of ints by saying vector⟨int⟩ v;
b) You add elements to a vector by saying v.push back(thing to be added);
c) You access elements of a vector with [ ] just like an array;
d) One of the vector member functions is .size().

- c++arrow_forwardIntegers 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 3arrow_forwardWrite the following function #input: a numerical vector x #output:the normalized vector, i.e. the vector rescaled into [0,1] # the formula to normalize is (x-min(x))/ (max(x)-min(x)) # you can NOT use the functions min and max # you can use %%, nrow, ncol, and length # you can write multiple functionsarrow_forward
- You may insert an element into an arbitrary position inside a vector using an iterator. Write a function, insert(vector, value) which inserts value into its sorted position inside the vector. The function returns the vector after it is modified. #include <vector>using namespace std; vector<int>& insert(vector<int>& v, int value){ ................ return v; }arrow_forward3. 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)arrow_forwardIntegers 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.
