- Write a C++ program define a vector object and initialize it with 3 values and then define an iterator that points to elements of this object, then ask the user to enter 3 more values and then add them to the previous vector and then print all elements in the vector.In c++ Write a function call X that receives two arguments: an array of vectors (generic type) and a generic variable called Y. The function returns the index of the vector (.e. the index of the vector in the array of vectors) that has the highest occurrence of the item. The function returns -1 if the element Y is not found on any vector.Write a C++ program that does the following steps: stores 16 integer random numbers in a vector container V. The random numbers range in value (0 – 199). One can generate such numbers by invoking the random number generation function, rand( ) and using the % (mod)operator Prior to using the rand( ) function, initialize the random number generator with the srand(17) Print the entire vector after filling the vector container V Create a function Total(vector iterator, Size) that returns the total sum of the vector V Count the number of values exceeding 85 and print the result Remove all numbers from the vector V that are divisible by 3 Print the entire modified reduced vector after the removal step Create a set S(descending order) from the modified vector V Print Set S Remove the first number in S that is divisible by 4 Print modified Set S
