Sep 24, 2013 · 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). long int is a synonym for long. Later on, long long was introduced to mean "long (64 bits) on Windows for real this time". long long int is a synonym for this.
The letters 100000000000 make up a literal integer constant, but the value is too large for the type int. You need to use a suffix to change the type of the literal, i.e. long long num3 = 100000000000LL; The suffix LL makes the literal into type long long. C is not "smart" enough to conclude this from the type on the left, the type is a ...
May 22, 2021 · The solution is either to use using instead of #define: using ll = long long; or to do (ll)a, since in this case the spaces are allowed. But if I were you, I would get rid of ll and use (long long)a, since ll is a rather non-descriptive name. Note that #define ll long long is a misuse of macros, and is bad for many reasons:
Mar 31, 2010 · On some systems, long is 64 bits. A lot of it depends on the processor architecture being targeted, and what its base word size is. The header limits.h exists to define the maximum capacity of the various types under the current compilation environment, and stdint.h exists to provide environment-independent types of guaranteed width, such as ...
May 14, 2010 · 6. LLONG_MAX gives the maximum value representable by a long long; if your implementation doesn't support long long, it shouldn't define LLONG_MAX. This isn't a perfect solution. long long isn't standard in C++03, and long long has been around longer than C99, so it's possible (and likely) that a compiler could support long long but not define ...
Sep 18, 2011 · 23. "a long in C/C++ is the same length as an int." Not always. The C++ standard specifies that an int be the "natural" size for the processor, which may not always be as big as a long. The standard also guarantees that a long is at least as long as an int, so the fact that they are equal sizes are not always guaranteed.
Nov 7, 2008 · 15. When compiling for x64, the difference between int and long is somewhere between 0 and 4 bytes, depending on what compiler you use. GCC uses the LP64 model, which means that ints are 32-bits but longs are 64-bits under 64-bit mode.
A guide of max values can be found below. The Max value of the default Int in Python 2 is 65535, anything above that will be a long. For example: >> print type(65535) <type 'int'>. >>> print type(65536*65536) <type 'long'>. In Python 3 the long datatype has been removed and all integer values are handled by the Int class.
20. To initialize long you need to append "L" to the end. It can be either uppercase or lowercase. All the numeric values are by default int. Even when you do any operation of byte with any integer, byte is first promoted to int and then any operations are performed. Try this. byte a = 1; // declare a byte.
For 32-bit systems, the 'de facto' standard is ILP32 — that is, int, long and pointer are all 32-bit quantities. For 64-bit systems, the primary Unix 'de facto' standard is LP64 — long and pointer are 64-bit (but int is 32-bit). The Windows 64-bit standard is LLP64 — long long and pointer are 64-bit (but long and int are both 32-bit).
