The first optional field in a conversion specification containsflag directives, zero or more flag characters that specify output justification and control output of signs, blanks, leading zeros, decimal points, and octal and hexadecimal prefixes. More than one flag directive may appear in a conversion...
Microsoft C/C++ features support for sized integer types. You can declare 8-, 16-, 32-, or 64-bit integer variables by using the__intntype specifier, wherenis 8, 16, 32, or 64. The following example declares one variable for each of these types of sized integers: C++Copy AI检测代码...

IsPow2(Int32) Determines if a value is a power of two. LeadingZeroCount(Int32) Computes the number of leading zeros in a value. Log2(Int32) Computes the log2 of a value. Max(Int32, Int32) Compares two values to compute which is greater. MaxMagnitude(Int32, Int32) Compares two...

Representations in memory, pointers, strings 在我们使用的64位系统中,地址用64位表示。但实际上机器上最大内存地址是47位。 对应2^47=128TB。一个程序是非常复杂的硬件和软件的组合,它只是一个巨大的字节数组的平铺空间。但实际上它在内存的不同区域之间移动。

32bit x86 can load 64bit integers in a single 64bit-load using MMX or SSE2movq. Handling 64bit add/sub/shift/ and bitwise booleans using vector instructions is more efficient (single instruction), as long as you don't need immediate constants or mul or div. The vector instructions with ...
On both 32-bit and 64-bit systems, the conversion specification of a 64-bit integer argument must include a size prefix of ll or I64. Otherwise, the behavior of the formatter is undefined. Some types are different sizes in 32-bit and 64-bit code. For example, size_t is 32 bits ...
