1. What are the 3 types of errors in programming? Explain each.
Multiple questions are asked so we will give you the answer to the first question only. Please upload another question again so that we can help you.
Type of errors in programming languages
Syntax errors
Errors generated when the syntax (or rules) of a particular language is not followed by the programmer. The program needs to be corrected in order to compile the program. This type of error is identified by the language compiler so it is also known as a compile-time error. The most common syntax errors are:
The semicolon is missing at the statement end in C/C++ or Java.
Using any variable without its declaration.
Missing parenthesis either open or close brace.
Logical Errors
This type of error arises due to wrong logic written in the program, therefore, wrong results are obtained which are not expected by the user. These errors are not identified by any compiler.
When the programmer is not able to understand the program specifications or lacking the usage of operators then these errors are produced.
Example,
When a user is asked to divide two integers but accidentally, he or she adds two integers then the compiler will not generate any error and the program gets executed successfully but the result obtained is not the expected one.
