Pass By Reference Practice Write the following functions for basic array operations based on the function descriptions given below.

Write the following functions for basic array operations based on the function descriptions given below.

1. FindMinArray: This function will search an array of integers (passed to the function as a parameter) for its minimum value, then return that value.

2. SumArray: This function will sum an array of integers (passed to the function through a parameter) then return that sum.

3. CopyArray: This function will copy an array (passed to the function as the first parameter) to another array (passed to the function as the second parameter)

4. SwapArray: This function will swap the values of two different arrays (passed to the function as two different parameters)

The output formatting and some variable declaration has already been done for you, fill in the rest.

//function for finding min
int findMin(int arr[], int size) {
        int min = arr[0];
        for(int i=1; i<size; i++) {

        return min;

//function for summing
int findSum(int arr[], int size) {
        int sum = 0;
        for(int i=0; i<size; i++) {
                sum += arr[i];
        }
        return sum;
}


//function for copying
