What is a program?

A sequence of instructions, which enables a computer to perform a desired task.

What is program input?

Program input is data sent to a computer for processing by a program.

Input can come in a variety of forms, such as tactile, audio, visual, or text.

What is the development process and what are its steps?

A development process that is iterative requires refinement and revisions based on feedback, testing, or reflection throughout the process. This may require revisiting earlier phases of the process.

1. Investigating and reflecting
2.Designing
3.Prototyping
4.Testing

What is program documentation?

A written description of the function of a code segment, event, procedure, or program, and how it was developed.

What types of error can occur when programing?

■ Logic error—This is a mistake in the algorithm or program that causes it to behave incorrectly or unexpectedly.
■ Syntax error—This is a mistake in the program where the rules of the programming language are not followed. '
■ Runtime error—This is a mistake in the program that occurs during the execution of a program. Programming languages define their own runtime errors.
