- 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

- 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
- 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

- 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
- unix - What is the difference between crlf and lf in effects and . . .
Then how is there difference between CRLF and LF? LF is the programming language standard for "new line" across all systems whereas CR is an artifact of the program that displays the text, usually a terminal Some systems (Windows) silently translate LF to CRLF in some situations, but treat CR regularly
