struct myStruct m = {.f = 10.11, .c = 'a', 6}; i is still initialized to 0. What is the reason if we do such compound initialization. c initialization structure c99 designated-initializer Share Improve this question Follow edited Aug 19, 2014 at 15:35 Shafik Yaghmour 157k4141 ...
Does this initialize the first object of the array only? If yes, is there a way to initialize ALL elements of the array to all the same values using that syntax (without calling a function/loop and without repeating the initializer)? c arrays struct initialization c99 Share Improv...
Starting from C99, we have designated initialization for struct, union and arrarys.. by struct foo foo = {.a=1}; and int a[] = {[2]=3}; Starting from C11, we have the anonymous unions(structs..) Starting from C99, we have bool(actually _Bool) type, which is not typedefd from...
Also known as the "struct hack". Allows the last member of a struct to be an array of zero length, such as int foo[]; Such a struct is commonly used as the header to access malloced memory. For example, in this structure, struct s { int n; double d[]; } S;, the array, d...
即使在今天,当我遇到C代码中的C99功能时,我有时会感到有些惊讶。 现在大多数主要编译器都支持C99(MSVC是一个值得注意的例外,而且一些嵌入式编译器也落后了),我觉得与C一起工作的开发人员可能应该知道他们可以使用哪些C99功能。一些功能只是之前从未标准化的常见功能(例如,...

Convert the struct i2c_msg initialization to C99 format. This makes maintaining and editing the code simpler. Also helps once other fields like transferred are added in future. Thanks to Julia Lawall <julia.law...@lip6.fr> for automating the conversion ...
