Is the size of long int and long long int the same?


Asked by Jolene Vazquez on Dec 05, 2021 FAQ



In some platforms, long long and long refer to the same size but in other platforms, long long can be double the size of long. In general, the rules are: signed and unsigned version will have the same size. size of int is 4 bytes. size of short <= size of int. size of int <= size of long.
Similarly,
The long data type is a 64-bit signed two’s complement integer. The long is a larger data type than int. The difference between int and long is that int is 32 bits in width while long is 64 bits in width.
Also Know, The size of the int type is 4 bytes (32 bits). The minimal value is -2 147 483 648, the maximal one is 2 147 483 647.
In this manner,
The size of the "int" integer type is 4 bytes and the size of the "long long" integer type is 8 bytes for all the above combinations of operating system and architecture. On Windows, the representation of "long double" may be increased to 10 bytes by use of the command line switch /Qlong-double. The corresponding memory allocation is 16 bytes.
And,
The size 4 is exactly the same size as multiple other purebaby items in a size 3. When I bought the issue to their attention via email it was evident that they really could not give two hoots. Really poor that customer loyalty means nothing and they couldnt step up and accept their own fault and fix it!!
