What is the difference between local and global variables?

• Local variables are declared outside of any function or block of code, while global variables are declared within a specific function or block of code.

• Local variables can be accessed from anywhere in the program, while global variables can only be accessed within a specific function or block of code.

• Local variables have a wider scope than global variables, allowing them to be used in multiple functions or blocks of code.

• Local variables are declared within a specific function or block of code, while global variables are declared outside of any function or block of code.

What is the difference between a syntax error and a runtime error?

• The difference between a syntax error and a runtime error is that a syntax error occurs during the compilation phase, while a runtime error occurs during the execution phase.

• A syntax error can be detected by the compiler, while a runtime error can only be detected during program execution.

• A syntax error is caused by a typo or incorrect syntax, while a runtime error is caused by logical errors or invalid operations.

• A syntax error occurs when there is a mistake in the code, while a runtime error occurs when the code is being executed.
