· here is my small program where i intently put the place holder %lf in the second printf. 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. · in c89, %lf caused undefined behaviour although it was a common extension to treat it as %f. C语言问题%f和%lf的区别由于精度的原因，输出%lf和%f的数据不同，可能会造成错误。 主要有一下四点区别：1、代表的数据类型不同%f代表单精度浮点型数据（float），%lf代表双精度浮点 … · 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 … · 1. 在这里l和l没有区别，都是一个意思，%lf 中间的l 是 long的意思。 %f输出的是 float类型的数，long 就是增加可输出的范围，表示double类型。 This is why also you never see %hd because it works … %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. · id like to know the difference (with examples if possible) between cr lf (windows), lf (unix) and cr (macintosh) line break types. The reason that one specifier can be used for two different types in printf is … This means that both float and double reach printf as double and therefore %f and %lf both expect double and therefore are the same. Why the second printf has the same result as the first printf( both printf 1. 3). 4、知识延展：c语言是一种计算机 程序设计语言，它既具有 高级语言 的特点， 又具有 汇编语言 的特点。它由美国贝尔研究所的d. m. ritchie于1972年推出， 5、1978年后，c语言已先后被移 …
