How many character include in an identifier name in C?
The C99 standard (ISO/IEC: 9899:1999) has the following to say on the matter:
5.2.4.1 Translation limits
The implementation shall be able to translate and execute at least one program that contains at least one instance of every one of the following limits:
- 127 nesting levels of blocks
- 63 nesting levels of conditional inclusion
- 12 pointer, array, and function declarators (in any combinations) modifying an arithmetic, structure, union, or incomplete type in a declaration
- 63 nesting levels of parenthesised declarators within a full declarator
- 63 nesting levels of parenthesised expressions within a full expression
- 63 significant initial characters in an internal identifier or a macro name (each universal character name or extended source character is considered a single character)
- 31 significant initial characters in an external identifier (each universal character name specifying a short identifier of 0000FFFF or less is considered 6 characters, each universal character name specifying a short identifier of 00010000 or more is considered 10 characters, and each extended source character is considered the same number of characters as the corresponding universal character name, if any)
- 4095 external identifiers in one translation unit
- 511 identifiers with block scope declared in one block
- 4095 macro identifiers simultaneously defined in one preprocessing translation unit
- 127 parameters in one function definition
- 127 arguments in one function call
- 127 parameters in one macro definition
- 127 arguments in one macro invocation
- 4095 characters in a logical source line
- 4095 characters in a character string literal or wide string literal (after concatenation)
- 65535 bytes in an object (in a hosted environment only)
- 15 nesting levels for #included files
- 1023 case labels for a switch statement (excluding those for any nested switch statements)
- 1023 members in a single structure or union
- 1023 enumeration constants in a single enumeration
- 63 levels of nested structure or union definitions in a single struct-declaration-list
Footnote: Implementations should avoid imposing fixed translation limits whenever possible.
There is no practical reason to impose these limits within the compiler let alone to make these limits available to the programmer, hence there is no standard header that defines them. Even if there were, the information is of no use to you let alone to the compiler, given that the compiler cannot arbitrarily change your identifier name lengths to suit. After all, those identifiers are supposed to be portable!
If translation limits do exist for your specific compiler, then it should be documented. A C99 compliant compiler must meet (or exceed) the limits defined by the C99 standard but those limits are such that "ordinary", portable code should never exceed them. After all, an identifier is only useful if it is readable, but if you have several identifiers such that the first 63 characters are an exact match then your code is anything but readable.
What file system supports up to 2 TB?
FAT32 claims to be able to support up to 2 TiB partitions, but does so at the cost of tremendous slack waste and an enormous file allocation table. NTFS is a completely different file system, but since it was designed at a time when hard disk sizes were measured in single gigabytes, there's no real way to know how well it will scale to disk volumes that are thousands or even millions of gigabytes in size.

Are Macs really better than PCs when you don't play video games?
Yes, they most definitly are. Aside from never being targeted with Viruses and thus not needing anit-virus software. They run faster, are more efficient, and are much more user friendly.

Here's an even better way, that works every time.
Windows does something very sneaky with Live Messenger to avoid having you (or anyone else for that matter) remove their program. They hide messenger under an umbrella in the remove programs panel.
Step 1) open your control panel. Step 2) Open Uninstall programs Step 3) Scroll down until you get to "Windows Live Essentials". Uninstall it. Step 4) You'll see a series of things to uninstall. Check any of the programs you want to remove and then do so.
Ta Dah! No more pesky Windows Live Messenger to crash your computer, or otherwise bug you with constant updates and startups.

What file formats are similar to TIFF?

Which situation Address Resolution Protocol used?
ARP used for resolving mac address from ip address, say one client want to communicate with another and the sender knows only its destination IP address. For communication it requires the physical address of the destination, thus sender uses ARP protocol to resolve the physical address of the destination from ip address by sending arprequest to destination system.

Second in command to the sultans?
The second in command to the sultans, often referred to as the "vizier" or "grand vizier," played a crucial role in the administration of the state, advising the sultan and overseeing government affairs. This position was typically held by a trusted advisor or noble with significant political influence and responsibilities, including military leadership and legal matters. The vizier acted as the sultan's representative, especially in matters of governance and diplomacy, while also managing the day-to-day operations of the empire. In some cultures, the vizier's authority could rival that of the sultan, depending on the political dynamics of the time.
What is a CMOS checksum error?
First cause is possibly a hardware change. Reboot at least once to see if the message clears. The most likely cause is the CMOS battery getting weak or has lost its power. This can be changed according to your motherboard's manual. Other much less likely causes I've seen reported are new hardware being incompatible or faulty, or a motherboard faulty. These can cause you to panic but are not the likely cause, but should not be ruled out. Try the battery replacement first.
How do i create limited user account which can't modify administrator files?
