In Win32, size_t is defined as unsigned int, unsigned int and size_t are all 4 bytes long. In X64, unsigned int is a 32 bit type and size_t is a 64 bit type. If we pass a X64 int (4 bytes) as size_t (8 bytes) to a function which requires a 64bit size_t, we ...
I mean, in a 64-bit system one can alloccate much more memory than 3GB, but what's the limit for a single array? In all the cases I am referring to dynamic allocation, using ALLOCATABLE arrays. Thanks! Kostas Translate Tags: Intel® Fortran Compiler0...

在64位机器上,我支持unsigned long long,我需要将这个值赋给一个可以在32位机器上访问的varriable,例如: - typedef struct { unsigned int low; unsigned int high; } myint64_t; myint64_t app_sc; Run Code Online (Sandbox Code Playgroud) 以下是64位机器的代码片段: unsigned long long sc; /*...
数值型可以以指定为无符号(unsigned),表示不取负数。 黄色表示常用。 数值类型 bit(M) m指定位数,默认为一。 二进制数,m的范围1–64数值范围0–2^m-1 tinyint 1字节 smallint 2字节 int 4字节 bigint 8字节 float(m,d) 4字节 单精度,m指定长度,d指定小数位数,会发生精度丢失。 double(m,d) 8字节...
voidfoo(unsignedint) {} voida(constchar*str) { foo(strlen(str)); } 这段代码在 32-bit 模式下降顺利通过编译, 但是在 64-bit 模式下, vs 编译器产生如下警告: error C2668: 'foo' : ambiguous call to overloaded function .\xxxx.cpp(16): could be 'void foo(unsigned int)' ...
