Syntax vs Semantics Error

"what is syntax and semantics errors? give examples in different languages."

Syntax errors and semantic errors are two types of errors that can occur in programming languages.

Syntax errors occur when the code violates the rules of the programming language. For example, if you forget to close a parenthesis or a quotation mark, the code will not run due to a syntax error. Syntax errors are usually caught by the compiler or interpreter when the code is being compiled or executed.

Here are some examples of syntax errors in different programming languages:

- In Python, forgetting to close a parenthesis:

print("Hello, World!'

- In JavaScript, forgetting to close a curly brace:

function addNumbers(x, y {
  return x + y;
}

- In C++, forgetting to include a semicolon:

c++
#include <iostream>
using namespace std;

int main() {
  cout << "Hello, World!" << endl
  return 0;
}

Semantics errors occur when the code is syntactically correct but does not do what the programmer intends it to do. For example, if you write a program that is supposed to add two numbers but instead subtracts them, the program will run without any syntax errors, but the output will not be what you expected.

Here are some examples of semantic errors in different programming languages:

- In Python, accidentally subtracting two numbers instead of adding them:

a = 5
b = 3
result = a - b
print(result)   # Output: 2

- In JavaScript, using the wrong comparison operator:

let age = 20;
if (age = 18) {
  console.log("You are old enough to vote!");
} else {
  console.log("You are not old enough to vote.");
}

- In C++, using the wrong variable in a calculation:

c++
#include <iostream>
using namespace std;

int main() {
  int x = 5;
  int y = 2;
  int z = x / y;
  cout << "z = " << z << endl;   // Output: z = 2
  return 0;
}

It's important to note that although syntax errors are easier to catch and fix than semantic errors, both types of errors can cause problems in your code and should be avoided.
