Padding at the end of structures
|
| |
§6.7.2.1 allows, but does not require, padding at the end of a structure or union. Logically, such padding is required to ensure proper alignment of elements in an array of structures. Take the following declaration: struct foo { int i; char c; } bar[2]; Assuming a four-byte alignment requirement for int, and hence for struct... more »

Formal definition of restrict
|
| |
6.7.3.1p3 from "Formal definition of restrict" says In what follows, a pointer expression E is said to be based on object P if (at some sequence point in the execution of B prior to the evaluation of E) modifying P to point to a copy of the array object into which it formerly pointed would change the value of E.122) Note... more »

%a correctly rounded to specified precision
|
| |
Given an IEEE 754 double implementation, ...int main (void) { printf ("%.2a\n", DBL_MAX); return 0; ...the correctly rounded value of DBL_MAX the given precision, whilst still being representable as a double, is +infinity in round-to- nearest mode. Is the intent of the standard that in this case text like "inf" (etc)... more »

Vector code in C
|
| |
Hi The preview of the X86 processor features for 2010 shows a 256 bit register file (called YMM) that will be able to do SIMD of 4 double precision data or 8 single precision data at a time. In this context, I would be interested to know if there are any extensions proposed or planned by the standards... more »

Determining if an n-ary tree is balanced or not.
|
| |
I am trying to determine if an n-ary tree is balanced or not, I have been stuck trying several approaches and am getting nowhere. My new thought is that i will have to step through each node of the tree, and compare the lengths of the roots of the children, making sure there is not a difference greater than one in the values for all of the... more »
