Chapter # 01:       Problem Solving

  1. Define Problem Identification.
  2. Define Desk Checking.
  3. Define Flow Chart.
  4. Define Algorithm.
  5. Write Two Advantages of Flow Chart.
  6. Define Bug.
  7. Define Debugging.
  8. Define Syntax.
  9. How Many Types of Bugs?
  10. Difference Between Logical Error and syntax Error.
  11. Define Run Time Error.

Answer: A run-time error occurs when program directs the computer to execute an illegal or undefined operation. When run-time error occurs, computer stops executing the program and displays a diagnostic message that helps in locating the error. Dived a number by zero or using a color statement is screen 2 are the important causes of run-time error.
