It also does not apply when «long» is used as a premodifier of a verb, participle, adjective, preposition or adverb with the sense «for a long time». As to the difference between the two sets, the C++ standard mandates minimum ranges for each, and that long long is at least as wide as long. From Old French long, a back-formation from longe, longue, the feminine form of Early Old French lonc, from Latin longus. From Middle English longe, lange, from Old English longe, lange, from the adjective (see above). The word shows the regular historical change of a to o before certain consonant clusters such as ng (compare with other examples in Middle and Modern English such as bond, song, throng, and wrong). The o-form may have also been reinforced by Old French long, from Latin longus, from the same Indo-European word.
English
This doesn’t necessarily mean that a long long is wider than a long. Many platforms / ABIs use the LP64 model – where long (and pointers) are 64 bits wide. Win64 uses the LLP64, where long is still 32 bits, and long long (and pointers) are 64 bits wide. The meanings of pine and long largely overlap; however, pine implies a languishing or a fruitless longing for what is impossible. Although the words hanker and long have much in common, hanker suggests the uneasy promptings of unsatisfied appetite or desire. This restriction does not apply when «long» is modified by an adverb such as too or enough.
Word History
Note the distinction there between the specifier and the type. The specifier is how you tell the compiler what the type is but you can use different specifiers to end up at the same type. Both hunger and thirst imply an insistent or impatient craving or a compelling need. Inherited from Old French long, from longe, longue, feminine of lonc, lunc, from Latin longus.

Long is equivalent to long int, just as short is equivalent to short int. A long int is a signed integral type that is at least 32 bits, while a long long or long long int is a signed integral type is at least 64 long term debt to total asset ratio bits. I am transitioning from Java to C++ and have some questions about the long data type.
adverb
When definingint n;you could translate this with «give me the best compromise of bitwidth and speed on this machine for n». Maybe in the future you should expect compilers to translateintto be 64 bit. So when you want your variable to have 32 bits and not more, better use an explicitlongas data type.
In Java, to hold an integer greater than 232, you would simply write long x;. However, in C++, it seems that long is both a data type and a modifier. The words yearn and long are synonyms, but do differ in nuance. Specifically, yearn suggests an eager, restless, or painful longing.

Historically, in early C times, when processors had 8 or 16 bit wordlength,intwas identical to todays short(16 bit). In a certain sense, int is a more abstract data type thanchar,short,longorlong long, as you cannot be sure about the bitwidth. Some common synonyms of long are hanker, hunger, pine, thirst, and yearn. While all these words mean «to have a strong desire for something,» long implies a wishing with one’s whole heart and often a striving to attain. In terms of long double, that’s actually a floating point value rather than an integer. Similarly to the integral types, it’s required to have at least as much precision as a double and to provide a superset of values over that type (meaning at least those values, not necessarily more values).
Hanker suggests the uneasy promptings of unsatisfied appetite or desire. While in Java a long is always 64 bits, in C++ this depends on computer architecture and operating system. For example, a long is 64 bits on Linux and 32 bits on Windows (this was done to keep backwards-compatability, allowing 32-bit programs to compile on 64-bit Windows without any changes).
