初始化系列之零初始化(zero initialization) 零初始化 把一个对象的初始化值设置为0 说明 零初始化会在下面的情况下执行: 对于任何static或者thread-local变量,没有使用const,在任何初始化之前,会进行0初始化,也就是static和thread-local修饰的变量会0初始化 如果不是类,作为数值初始化序列的一部分;如果是类,并且...
The effects of zero-initialization are: IfTis ascalar type, the object is initialized to the value obtained byexplicitly convertingthe integer literal0(zero) toT. IfTis a non-union class type: allpadding bitsare initialized to zero bits, ...

I'd love to know what the guaranteed and actual behavior are wrt zero initialization and if there is any switch for getting local arrays zero initialized.We are migrating some VAX FORTRAN applications that exploit the default zero initialization that the VAX (but not AXP!) did for scalars an...
Zero Initialization of POD and Scalar TypesArticle 11/16/2012 POD and scalar types will always be zero initialized if instantiated with the default constructor syntax. Copy struct S { void *operator new (unsigned int size, void*p, int i) { ((S*)p)->i = i; return p; } int i; ...

Hi,I am trying to perform hybrid initialization in fluent for a thermo-fluid problem but am getting 0 residuals in it. I have been told th meshing could be an issue and so I have tried to reduce the element size in meshes and it still fails and gives 0 r
