Types of Errors

Question 1

What are the three main types of errors in programming?

Answer 1

Syntax Errors, Logic Errors, Runtime Errors

Each type has distinct characteristics and implications.

Question 2

Define Syntax Errors in programming.

Answer 2

Mistakes in the use of the language of the program that prevent successful compilation or interpretation

Question 3

Give an example of a Syntax Error.

Answer 3

Missing a semicolon at the end of a statement

This is similar to grammatical errors in a spoken language.

Question 4

What are Logic Errors?

Answer 4

Errors that occur when a program doesn’t perform as expected due to incorrect logic or algorithm

Code compiles and runs, but it doesn’t do what it’s supposed to do.

Question 5

Provide an example of a Logic Error.

Answer 5

Incorrectly using a < operator instead of <= in a loop condition

This can lead to an off-by-one error.

Question 6

What are Runtime Errors?

Answer 6

Errors that surface while the program is running, often due to illegal operations

These cannot be determined until the program is in progress.

Question 7

Give an example of a Runtime Error.

Answer 7

Trying to access an array element that is out of bounds

This may cause the program to crash or terminate unexpectedly.

Question 8

Why is it important to understand and identify different types of errors?

Answer 8

It is critical for debugging and ensuring the reliability and correctness of a program

Each type requires different strategies for detection and resolution.
