I have written a template class for a circular buffer: template <class T> class CRingBuffer { /* ... */ };
In ip_output there\'s 2 lines of code that I can\'t understand: mhlen = sizeof(struct ip) and if (hlen > sizeof(struct ip)) { ...
This will (hopefully) get solved pretty fast, this is my problem: I have a structure 开发者_开发知识库

When I give sizeof(a), where a=13.33, a float variable, the size is 4 bytes. But开发者_如何学C if i give sizeof(13.33) directly, the size is 8 bytes.
Why would sizeof in the following ca开发者_JS百科ses print different values: printf(\"%d\",sizeof(\"ab\")); //print 3
The output offollowing program #include<stdio.h> int main(){ int *p[10]; printf(\"%ld %ld\\n\",sizeof(*p),sizeof(p));
I\'m really new to C and all I know is that the error is related to oldname and newname not be initialized
