Create an interactive program using $1$ user defined function, $1$ counting loop, $1$ input validation loop, and an array.You need to create a program that fills in an array of doubles and calculates the average of the array. Declare the doubles array to be a size of $30.$ Ask the user for how many doubles they would like to add to the array $($maximum of $30,$ the size of the array$).$ Store this value into a variable called count. Implement a loop to make sure that the user enters a value within this range $(1-30).$ Fill the array in the main function with user input, one double at a time, before passing it to the Array$\_$Avg function. Store these doubles in an array called arr. The value of count and the array will be passed to a function called Array$\_$Avg. Return the average to the main function and print out the average.Please refer to the following prototype and example output.double Array$\_$Avg $($double arr$[],$ int count$)$;$//$prototype$//$Array$\_$Avg function takes in a double array $($double arr$[])$ and the number of doubles within the array $($int count$)$ from the main function$//$returns the average of the array $($double$)$ to the main function$//$the average of the array should be printed out by the main functionExample output:Please enter the number of elements in your array: $4$Please enter number $1$ out of $4$: $23\mathrm{.}5$Please enter number $2$ out of $4$: $45\mathrm{.}6$Please enter number $3$ out of $4$: $78\mathrm{.}9$Please enter number $4$ out of $4$: $110\mathrm{.}5$The average of the array is $64\mathrm{.}62$
