Operations of vector class

The vector class is available in Java and C++ programming languages. It is a class implementing a dynamic array. A dynamic array is an array whose size automatically increases when an element is added to it. The vector class stores elements in a contiguous memory block and assigns the memory to the elements whenever required during execution.

Your program should include the following functions:
1. Function called read is used to read the weight of the
packages from a file named "weights.txt" and store them
into an array called Packages. It returns the number of
package read from input file. The total number of packages
cannot be more than 100.
2. Function cal_Costs is used to calculate the cost of each
package and store it in another array called Cost based on
the following rules:
- If the weight is less than or equal to 1 KG, the cost is 3
OMR.
- If the weight is greater than 1 KG but less than or equal to
3 KG, the cost is 2.5 OMR for each KG.
- If the weight is greater than 3 KG, the cost is 1.9 OMR for
each KG.
This function also output the cost of each package and
total cost to the output file named "results.txt".

This function also output the cost of each package and
total cost to the output file named "results.txt".
3. Function Maximum is used to find the maximum weight
package and output the value of the maximum weight
package to the output file named "results.txt".
4. Function Search is used to output the total cost of all
packages less than the cost of maximum weight package in a
file called "results.txt".
Hint: Use the following function prototype.
int read(double 1);
void cal_Costs(double], double], int);
double Maximum(double ), int);
void Search(double ), double 1, int);
results.txt
weights.txt
Package 0 costs:5 OMR.
Package I costs:7.5 OMR.
Package 2 costs : 24.7 OMR.
Package 3 costs:3 OMR.
Package 4 costs:9.5 OMR.
Package 5 costs : 3.75 OMR.
Package 6 costs: 145.54 OMR.
Package 7 costs: 43.7 OMR.
And the Total Costs is: 242.69

Quantities that have magnitude and direction but not position. Some examples of vectors are velocity, displacement, acceleration, and force. They are sometimes called Euclidean or spatial vectors.

C++ Can someone help me with this problem? I have been trying it but it still doesn't work. Thank you
C++ Sort a vector Define a function named SortVector that takes a vector of integers as a parameter. Function SortVector() modifies the vector parameter by sorting the elements in descending order (highest to lowest). Then write a main program that reads a list of integers from input, stores the integers in a vector, calls SortVector(), and outputs the sorted vector. The first input integer indicates how many numbers are in the list. Ex: If the input is: 5 10 4 39 12 2 the output is: 39,12,10,4,2, For coding simplicity, follow every output value by a comma, including the last one. Your program must define and call the following function:void SortVector(vector<int>& myVec) #include <iostream>#include <vector>using namespace std; /* Define your function here */ int main() { /* Type your code here */ return 0;} Enter program input - 5 10 4 39 12 2
Is there any advantage to utilising vectors instead of arrays?
Recamán's sequence def recaman(n): Compute and return the first n terms of the Recamán's sequence, starting from the term a1 = 1.Note how the definition for the current next element depends on whether a particular number is already part of the previously generated part of the sequence. To let your function execute in a speedy fashion even when generating a sequence that contains millions of elements, you should use a set to keep track of which values are already part of the previously generated sequence. This way you can generate each element in constant time, instead of having to iterate through the entire previously generated list. The better technique that saves time by using more memory can create this list arbitrarily far in linear time, and should therefore be fast even for millions of elements, at least until it runs out of memory. n Expected result 10 [1, 3, 6, 2, 7, 13, 20, 12, 21, 11] 1000000 (a list of million elements whose last five elements are [2057162,1057165,…
Answer in C++ code please! (Duplicate Elimination with vector) Use a vector to solve the following problem. Read in 20 numbers, each of which is between 10 and 100, inclusive. As each number is read, validate it and store it in the vector only if it isn't a duplicate of a number already read. After reading all the values, display only the unique values that the user entered. Begin with an empty vector and use its push_back function to add each unique value to the vector.

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.
