Consider the program main() { printf(\"%d %d %d\",sizeof(\'3\'开发者_StackOverflow),sizeof(\"3\"),sizeof(3));
Sizeof() doesn\'t work when applied to bitfields: # cat p.c #include<stdio.h> int main( int argc, char **argv )
Tried to look for that and didn\'t find an answer. Can anyone help? Thanks.开发者_如何学运维There are DSPs that don\'t allow for integers of less than 32 bits. See this for instance.
Considering the following line: char *p = malloc( sizeof(char) * ( len + 1 ) ); Why is sizeof(char) used? It\'s not necessary, is it? Or Is it just a matt开发者_运维技巧er of style?
Consider the following code: template<bool> class StaticAssert; template<> class StaticAssert<true> {};
What will be equivalent of this in Java? for (i = (sizeof(num)*8-1); i; i--) 开发者_开发技巧 num is given number, not array. I want to reverse bits in integer.Java does not have sizeof. Arrays have
I\'ve noticed that in c/c++ a lot of Win32 API structs need to be told how big they are. i.e someStruct.pbFormat = sizeof(SomeStruct)开发者_JAVA技巧
I am just starting with cpp and I\'ve been following different examples to learn from them, and I see that buffer size is set in different ways, for example:
I just found this code on Wikipedia. Link: http://en.wikipedia.org/wiki/Sizeof#Use The code: /* the following code illustrates the use of sizeof
I have this situation where an EXE program imports a DLL for a single function call. It works by passing in a custom structure and returning a different custom structure. Up till now it\'s worked fine
