//Given an array with multiple values (e.g. [1,3,5,7,20]), write a program that prints the average of the values in the array. Again you're not to do this by using of any of the pre-built functions in Javascript. Again iterate through each number in the array and update the 'average' as the program retrieves each number in the array.

function averageArray(inputArray){

var sum=0;

for(i=0; i < inputArray.length;i++){

sum += inputArray[i]

}

console.log(sum/inputArray.length);

}

var x= [21,3,5,7];

averageArray(x);
