C++ question.

2-1 In your main function in main-2-1.cpp, define and initialise a single-dimensional integer array. Next, define a pointer that points to the first element in the array and pass the pointer to a function Signature: void print sevensCint nums, int length); Using only pointer variables (and looping constructs), print only the array values that are exact multiples of 7 from start to finish to standard output. The only program output should be the numbers, one per line with no white space. Note: before accessing an array element, the pointer must be changed to point to the element. You may not use the & operator or [ notation in your function 2-2 Write a function that given an array of integers, determines the maximum sum of any possible contiguous sub-array. If al the numbers are negative the result is O. Signature: int maximumsumCint *nums, int length); For example, for the array: 31, -41, 59, 26, -53, 58, 97, -93, -23, 84 the sub-array with the largest sum is: 59, 26, -53, 58, 97 The result would be: 187
