Write a function to find the maximum sum of a subarray within a given array of integers. The subarray should be contiguous, meaning the elements are adjacent to each other in the array. For example, given the array [-2, 1, -3, 4, -1, 2, 1, -5, 4], the maximum sum of a subarray is 6, which corresponds to the subarray [4, -1, 2, 1]. Write a function named maxSubarraySum that takes an array of integers as input and returns the maximum sum of a subarray. Note: If all the elements in the array are negative, the function should return 0. Example: Input: [-2, 1, -3, 4, -1, 2, 1, -5, 4] Output: 6 Input: [-1, -2, -3, -4] Output: 0 Write the maxSubarraySum function that solves this problem efficiently.

ASSIGNMENT: Working with Vectors Write a menu-driven program that will allow the user to run any of the following questions. Please put the functions headers in h file and the functions definitions in a .cpp file. 1. Write C++ code for a loop that simultaneously computes both the maximum and minimum element in a given vector. 2. Write a function double scalar_product(vector a, vector b) that computes the scalar product of two vectors. The scalar product of two vectors A[al, a2, a3) and B(bl, b2, b3} is another vector C given by C{c1, c2, c3} where cl = al * b1, c2 = a2 + b2, c3 = a3 + b3. 3. Write a function that computes the alternating sum of all elements in a vector. For example, if alternatingSum() is called with a vector containing 149 16 9 7 4 9 11 then it computes 1-4+9-16+9-7+4-9+11=-2 4. Write a procedure reverse that reverses the sequence of elements in a vector. For example, if reverse is called with a vector containing 1 49 16 9 7 4 9 11 then the vector is changed 11 9 4 7…

Use pointers to write a function that finds the larg- est element in an array of integers. Use {6, 7, 9, 10, 15, 3, 99, -21} to test the function.

You are designing a function that will manipulate an array of integers. It needs to work for arrays of any length. What is the minimum number of parameters your function will have?

Write a function that calculates the totals of the rows in a 2D array with 5 columns.  Store the row totals into a separate 1D array.  Pass both arrays into the function along with the number of rows in the 2D array.

Write a maxConsecutiveDiff function which returns the maximum difference between any two consecutive values in the array.Consecutive values are next to each other in an array (+/- 1 index)This function should accept all required data as parameters.ExamplesIf the array is 17 15 16 11 14 the maximum consecutive difference is 5 which is the difference between 16 and 11.If the array is 10 13 11 12 19 the maximum consecutive difference is 7 which is the difference between 12 and 19.
