note: second input from prompt

note: 200 value is already assign

function submitBtn() { let a = parseFloat(document.getElementById("demo").value); let b = parseFloat(prompt("Enter your second number", 200)); let c = a + b; alert("The result is: " + c); document.getElementById("result").innerHTML = c; }

Result will appear here

 // Direct Assign
