Take a screen shot of the program and the output and attach below: devops, The concept of a trailer record centers around the notion of selecting a field (a particular item of data) in the input record which will be used to indicate the end of data and then selecting a trailer value, also known as a sentinel value, which will never occur as normal data value for that field. For example, in this case, you should write a program that need not be modified every time the total number of students appearing in an examination changes. Have the program calculate the answers to the two arithmetic problems. In real-life applications, sometimes, you will need to change the sequence of execution according to conditions. I'm using Python requests library's source code. If the number is greater than 10, it displays its square and cube (See figure 2.12.). Click y and enter to proceed: 5. See the example below. Uploaded

Temporary data is stored in RAM, and long-term storage takes place on hard drives. In this method, the end of input data is marked by a trailer record, that is, the last data record in the input is followed by a record whose main purpose is to indicate that the end of the input data has been reached. The Python code that corresponds to this flow chart is: The description of another program is below: The program starts.
