An array (vector) is a common-place data type, used to hold and describe a collection of elements. These elements can be fetched at runtime by one or more indices (identifying keys). A distinguishing feature of an array compared to a list is that they allow for constant-time random acce...
A type-safe dynamic array implementation for C. Installation Thevec.candvec.hfiles can be dropped into an existing C project and compiled along with it. Usage Before using a vector it should first be initialised using thevec_init()function. ...

With dynamic arrays, you can write a single formula and get an array of values returned. One formula, many values. This will allow you to build more capable...

默认情况下new分配的对象都是默认初始化,但同时可以进行值初始化,同样是加括号即可,新标准还支持列表初始化(剩余元素值初始化,超出则抛出bad_array_new_length异常): int*pia1=newint[5];int*pia2=newint[5]();int*pia3=newint[5]{1,2,3}; ...
