有没有更好的方法来初始化C中分配的数组？

如何用另一种(也许更短的)方式写这个？
有没有更好的方法来初始化C中分配的数组？

int main(void) {
   int* a;
   a = new int[10];
   for (int i=0; i < 10; ++i) a[i] = 0;
}

解决方法

int *a =new int[10](); // Value initialization

ISO C第8.5 / 5节

To value-initialize an object of type T means:

— if T is a class type (clause 9) with a user-declared constructor (12.1),then the default constructor for T is called (and the initialization is ill-formed if T has no accessible default constructor);

— if T is a non-union class type without a user-declared constructor,then every non-static data member and base-class component of T is value-initialized;

— if T is an array type,then each element is value-initialized;

— otherwise,the object is zero-initialized
