If someone can please help me with arrays using C++ code, I am still confused on how arrays work. It would be appreciated if you explain the code being done and its pupose if possible, thank you.

Implement a function that determines if an array of int is lucky. The function returns true if the array passed into it contains at least one 7 and no 13's; otherwise it returns false. A declaration of the function is shown below. bool isLucky (int a, int len) Implement a function that counts the number of negative integers in a two-dimensional array with 100 rows and 100 columns. The function takes a two-dimensional array of int and returns the number of negative numbers in it. A declaration of the function is shown below. int countNegatives(int a[100] [100]); Write a function called isStrictlyincreasing that checks whether an array of integers contains values that are in strictly increasing order. A declaration of the function is shown below. The function returns true if the elements are in strictly increasing order; otherwise it returns false. For example, it will return true for (-2, 4, 5, 6, 8) and it will return false for (3, 4, 6, 6, 9) bool isStrictlyIncreasing(int a, int len)
