Question

in C++ and also each function has its own main function so please do the main function as well. Previously when i asked the question the person only did the function and didn't do the main function so please help me do it.

1-1. Write a function that returns the sum of all elements in an int array. The parameters of the function are the array and the number of elements in the array. The function should return 0 if the size parameter, n, is less than 1. Signature: int sum_array(int array[], int n) (Note. This program should be in the file function-1-1.cpp and the main function that call it should be in the file main-1-1.cpp) 1-2. Write a function that returns the average of all elements in an integer array. The function takes as parameters the array and the number of elements in the array. Your function should return 0.0 if the size parameter, n, is less than 1. Hint: What's the difference between an integer and a double? You might need to look up how to cast a variable from one data type to another. Signature: double average(int array[], int n) 1-3 Write a function that returns the number of elements in an array that are equal to a given parameter. The function should take as parameters the array, its size, and the desired number. The function should return 0 if the size parameter, n, is less than 1. Signature: int count(int array(), int n, int number) 1-4. Write a function that returns the sum of two arrays as an integer (of equal size). The function should take as parameters an array, another array and their size. Hence the result is sum of array 1 + sum of array 2. The function should return O if the size parameter, n, is less than 1. Try to do this in one for loop. Signature: int sumtwo(int array[], int secondarray(), int n)
