- c - Why does scanf () need %lf for doubles, when printf () is okay . . .
%f for float %lf for double %Lf for long double It just so happens that when arguments of type float are passed as variadic parameters, such arguments are implicitly converted to type double This is the reason why in printf format specifiers %f and %lf are equivalent and interchangeable In printf you can "cross-use" %lf with float or %f with
- Difference between CR LF, LF and CR line break types
I'd like to know the difference (with examples if possible) between CR LF (Windows), LF (Unix) and CR (Macintosh) line break types
- Correct format specifier for double in printf - Stack Overflow
20 Format %lf is a perfectly correct printf format for double, exactly as you used it There's nothing wrong with your code Format %lf in printf was not supported in old (pre-C99) versions of C language, which created superficial "inconsistency" between format specifiers for double in printf and scanf
- 大神们，C语言%f和%lf有什么区别? - 知乎
f表示float，lf表示double，但是printf中实际上只有f没有lf，后来加上了也并没有任何区别。 为什么printf会有这样的行为，是因为printf的函数签名是变长参数的，而变长参数，因为双方无法确定每一个参数的长度，所以参数在传递时会提升，所有未知类型的参数都会被提升到64位，而被调用者也就只需要
- c - What is the difference between %0. 2lf and %. 2lf as printf . . .
This means that both float and double reach printf as double and therefore %f and %lf both expect double and therefore are the same This is why also you never see %hd because it works exactly the same as %d Additionally this is why you don't need to cast a char to int if it is given to %d
- Row terminators for text files used for bulk insert
The docs say – and this is really something – that specifying \n splits rows at \r\n When you specify \n as a row terminator for bulk import, or implicitly use the default row terminator, bcp and the BULK INSERT statement expect a carriage return-line feed combination (CRLF) as the row terminator If your source file uses a line feed character only (LF) as the row terminator - as is
- How to fix Git warning: LF will be replaced by CRLF
A script I was using was changing line endings from CRLF to CR The command git diff outputs a similar message LF will be replaced by CRLF the next time Git touches it for each file The message is sent to stderr, so to supress the message use git diff 2> dev null
