How do I create a web page that lets a user enter as many values as they wish until the entry of a 0. Then find the sum and the average of all the numbers and show sum and average on screen. In code?

You could do this using Javascript.1) create a textfield2) create a submit button3) define two Javascript variables: a running tally, and a click-counter4) give the button an onclick event that calls a function that works like this:read the value from the text fieldconvert it to a numeric valueif that value is 0 {if the counter != 0 {display the tally and the average (which equals tally over counter)}else{either display an error message, or 0 as both the tally and average - to your taste.}reset both the tally and the counter to 0}else{add the value to the tallyincrement the counter by 1}And here's a working example of how to do it:span.buttonClass{background-color: #C8C8C8;padding: 4px;border-width: 2px;border-style: outset;font-weight: bold;}The Summinator!var tally = 0, counter = 0;function addValue(){var textfield = document.getElementById("addVal");var avgfield = document.getElementById("avgfield");var sumfield = document.getElementById("sumfield");var num = parseFloat(textfield.value);var sum, avg;textfield.value = '';if(isNaN(num)){ // make sure they entered a numberalert("Please enter a numeric value.");}else{if(num != 0){tally += num;counter ++;sumfield.textContent = "";avgfield.textContent = "";}else{if(counter == 0){sum = avg = 0;}else{sum = tally;avg = tally / counter;}sumfield.innerHTML = "The sum is " + sum;avgfield.innerHTML = "The average is " + avg;tally = counter = 0;}}}Add ValueYou can even make it a little nicer by having it output the sum and average each time a number is entered, rather than waiting for the zero input (which would still reset things). That actually simplifies the code too, and would look like this:...if(isNaN(num)){ // make sure they entered a numberalert("Please enter a numeric value.");}else{if(num != 0){tally += num;counter ++;sum = tally;avg = tally / counter;}else{sum = avg = tally = counter = 0;}sumfield.innerHTML = "The sum is " + sum;avgfield.innerHTML = "The average is " + avg;}...
