23 Literal suffixes for (signed) size_t(P0330R8) 这个特性为std::size_t增加了后缀uz,为signed std::size_t加了后缀z。 有什么用呢?看个例子: 这代码在32 bit平台编译能够通过,而放到64 bit平台编译,则会出现错误: 在32 bit平台上,i被推导为unsigned int,v.size()返回的类型为size_t。而size_t在...

Here, 18 is a literal, a value that is expressed as itself whereas a constant can be considered a data type that is substituted in place of a literal to enhance the functionality of the code. Now, we wish to print the message, “ You are allowed to vote! ” for people of age great...
You can also use type suffixes with integer values to make it easier for the compiler to understand the type of the integer value. If you follow the value with L, the compiler will treat it as a long value. If you add U after the value, the compiler treats the value as unsigned.Fo...

Assembler source files, with .s suffixes After linking, the C compiler places the linked files, now in executable code, into a file named a.out, or into the file specified by the -o option. When the compiler produces object code for each .i or .c input file, it always creates an ob...
