what kind of program construct has a looping branch of code?

Answer 1

A program construct that features a looping branch of code is typically referred to as a loop. Loops allow a section of code to be executed repeatedly based on a specified condition. There are several types of loops commonly found in programming:

1. For Loop: A loop that runs a specific number of times. It often uses a counter to control the number of iterations.

   for i in range(5):
       print(i)
   

2. While Loop: A loop that continues to execute as long as a specified condition remains true.

   i = 0
   while i < 5:
       print(i)
       i += 1
   

3. Do-While Loop: A variation of the while loop that executes the loop body at least once before checking the condition at the end.

   do {
       console.log(i);
       i++;
   } while (i < 5);
   

4. Enhanced For Loop (or For-Each Loop): This type of loop is used to iterate over elements in a collection or array.

   for (String item : list) {
       System.out.println(item);
   }
   

All of these constructs enable repeated execution of code, making them essential for tasks that require iteration, such as processing arrays, lists, or handling repetitive user input.
