Question

Tiffany is writing a program to help manage a bake sale. She writes the following code which prompts the user to enter the total number of items a person is buying and then a loop repeatedly prompts for the cost of each item. She wrote the code but there is a problem: it runs in an infinite loop. How can Tiffany change her code so it doesn't loop forever?

Answer 1

Answer:

Add the following code after the line 3 that is:

numItems = numItems - 1;

Explanation:

In the following question, some information in the question is missing that is code block.

0 var numItems = promptNum("How many items?");

1 var total = 0;

2 while (numItems > 0){

3 total = total + promptNum("Enter next item price");

4 }

5 console.log("The total is" + total);

In the following scenario, Tiffany is developing a program to help with the handling of bake sales and she not write that part which is essential.

There would become an incorrect condition that requires any increment/decrement operations stating that perhaps the condition variable will be incorrect. Because there has to be the variable "numItems" operation because it engages in the while loop condition.
