C does not provide direct support to exception handling: it is the programmer's responsibility to prevent errors in the first place and test return values from the functions. In any case, a possible way to implement exception handling in standard C is to use setjmp/longjmp functions:
Handling errors in this manner is considered bad practice [1] and an anti-pattern in computer programming. In languages with exception handling support, this practice is called exception swallowing. Errors and exceptions have several purposes:
in place of the hostname. The string "localhost" will attempt to access the file as UNC path \\localhost\c:\path\to\the file.txt, which will not work since the colon is not allowed in a share name. The dot "." results in the string being passed as \\.\c:\path\to\the file.txt, which will work for local files, but not
Common exceptions include an invalid argument (e.g. value is outside of the domain of a function), [5] an unavailable resource (like a missing file, [6] a network drive error, [7] or out-of-memory errors [8]), or that the routine has detected a normal condition that requires special handling, e.g., attention, end of file.

This path refers to a file called File.txt located in the parent directory of the current directory on drive C:. Folder\SubFolder\File.txt This path denotes a file called File.txt located in SubFolder directory which in turn is located in Folder directory which is located in the current directory of the current drive (since this example gives ...

Note that the examples given there do not work as-is on modern Windows systems (post XP SP2) due to the changes Microsoft made to address the security issues present in the early SEH design.
The conditional expression syntax does not follow this rule. ^b This is pattern matching and is similar to select case but not the same. It is usually used to deconstruct algebraic data types. ^c In languages of the Pascal family, the semicolon is not part of the statement. It is a separator between statements, not a terminator.
