Syntax Error: error due to missing colon, semicolon, parenthesis, etc. Syntax is the way in which we construct sentences by following principles and rules.
Example: In C++, it would be a syntax error to say
int x = "five";
This will not compile because it does not follow the syntax of the language and does not make any sense to the compiler.
Semantic Error: it is a logical error. it is due to wrong logical statements. Semantics is the interpretations of and meanings derived from the sentence transmission and understanding of the message. Semantics errors are Logical, while Syntax errors are code errors.
Example: A semantic error would compile, but be incorrect logically:
const int pi = 12345;
Your program will likely compile and run without error but your results will be incorrect. (Note that these types of errors are usually much harder to debug)

What is Semantic errors in c?
A semantic error is a logic error. That is, the code may compile and run, but does not perform as you intended. Some semantic errors can be picked up by the compiler, often shown as warning, such as: if (x = 5) // warning: did you mean x == 5? Others are simply impossible for the compiler to spot: int x, y, z; // ... ++z; // add 1 to x In the above code, we meant to increment x, but incremented z instead. The compiler won't notice the error so this will inevitably lead to a runtime error.
What is logical errors in vb?
Logical errors in Visual Basic (VB) occur when the code runs without crashing, but produces incorrect or unintended results. These errors stem from flaws in the program's logic, such as using the wrong operators, incorrect conditional statements, or faulty algorithms. Unlike syntax errors, which prevent the code from compiling, logical errors can be more challenging to identify and debug, often requiring careful testing and analysis of the program's flow and output.
What is semantic analysis in compiler?
Semantic analysis in a compiler is the phase that checks the source code for semantic consistency and correctness after the syntactic structure has been analyzed. It involves verifying type compatibility, ensuring variable declarations are used correctly, and checking for other semantic rules specific to the programming language. This phase helps identify errors that cannot be detected by syntax analysis alone, such as type mismatches or scope violations. Ultimately, it prepares the abstract syntax tree for the subsequent code generation stage.
Example of semantic errors?
scores = [51, 47, 53, 97, 27]summation = 0.0for score in scores:summation *= score # Semantic Error.average = summation / len(scores)print average # Isn't average. average == 0
Examples of logical errors in c program?
Logical errors :- These errors occur because of logically incorrect instructions in the program. Let us assume that in a 1000 line program, if there should be an instruction, which multiplies two numbers and is wrongly written to perform addition. This logically incorrect instruction may produce wrong results. Detecting such errors are difficult.
How computer handle semantic error?
Semantic error are logical errors. That does mean, it would compile and run without errors. But, the output would be different from the expected output.
What is lexical and semantic errors?

What are the classifications of program bugs?
Some common types of program bugs are: Arithmetic bugs Logic bugs Syntax bugs Resource bugs Multi-threading programming bugs Interfacing bugs Performance bugs Teamworking bugs
How do you understand errors?
Errors are bugs or mistakes.It coulb be syntax or semantic in nature.
What is the difference between a compilation error and logic error?
errors which come during compilation is known as compilation error. here we get syntax errors only not logical errors like division by zero. logical error occur during run time example:if you write a program for division with zero you will not get compilation error but during execution you will error

What are the different types of bugs that can affect software development?
There are several types of bugs that can affect software development, including syntax errors, logic errors, runtime errors, and semantic errors. Syntax errors occur when code is not written correctly according to the programming language rules. Logic errors occur when the code does not produce the expected output due to flawed reasoning. Runtime errors occur during the execution of the program and can cause it to crash. Semantic errors occur when the code runs without errors but does not produce the desired outcome.
What are mistakes that cause a running program to produce incorrect results called?
Semantic errors
Why do humans make logical errors in problem solving and decision making?
humans do logical errors in problem solving and decision making because of non-existence of sufficient ....WISDOM.
What is the difference between ECC and parity memory?
ecc momory can detect and repair errors
What is the difference between formal and informal fallacies?
Formal fallacies are errors in the structure of an argument, while informal fallacies are errors in the content or reasoning of an argument.
What is the difference between solipsism and solipcism?
There is no difference between "solipsism" and "solipcism"; they are likely just spelling errors of the same term, which refers to the philosophical idea that only one's mind is sure to exist or the view that the self is all that can be known to exist.
