Explanation of Solution

“while” loop:

  • The “while” loop is used to execute the code repeatedly, if the condition is satisfied. Otherwise, it exits the loop, and hence it is also called as indefinite or conditional loop.
  • There is no guarantee about how many times the loop will execute.
  • The syntax for “while” loop is as follows:

  while condition:

  # body

Example in Java   Write and trace sentinel-controlled while loop.
Draw a flow chart for Do-While loop ( in c++ ) for controlled/uncontrolled infinite loop iterations.
For this question you must design and implement a postcondition loop in Python that will display the following numbers (one on each line) to the terminal:   29, 41, 53, 65, 77, 89, 101, 113, 125, 137, 149, 161, 173, 185, 197, 209, 221, 233, 245, and 257.   Although a counter-controlled loop is ideal for this task, you are not permitted to use a FOR loop in your program - you must use a postcondition loop that has been implemented using WHILE instead.Furthermore, your postcondition loop must be implemented using a Boolean flag variable.
