Description: (Process scores in a text file) Suppose that a text file contains an unspecified number of scores. Write a program that reads the scores from the file and displays their total and average. Scores are separated by blanks. Your program should prompt the user to enter a filename. Here is a sample run: Enter a filename: scores.txt There are 70 scores The total is 800 The average is 33.33

Key Concepts

Text File Parsing

Text file parsing is the method of reading and interpreting data stored in text files, usually by breaking the text into meaningful components or tokens. When values in a file are separated by known delimiters like spaces, the program can split the file content efficiently to extract individual elements for further processing.

File Input/Output

File I/O involves reading data from or writing data to files stored on a disk. It is a fundamental concept in programming that allows programs to persist data between executions, process external data inputs, and handle large data sets. In many cases, reading from a file involves opening the file, processing its contents, and closing the file properly to free resources.

User Input Handling

User input handling is the process of accepting data or commands from the user during the execution of a program. This often involves prompting the user for information—such as a filename or other parameters—and then using that input to control program behavior or processing paths.

Aggregation and Calculation

Aggregation involves combining multiple data points to compute a summarized result, such as a total or an average. This concept is essential in data analysis and statistics, where individual numbers are often processed to deliver insights like sums, means, or other statistical measures, which then provide a more comprehensive overview of the data set.
