Initialize An Array In C Scaler Topics
A declaration of the form T a N declares a as an array object that consists of N contiguously allocated objects of type T The elements of an array are numbered 0 N 1 and may be accessed with the subscript operator as in a 0 a N 1 Arrays can be constructed from any fundamental type except void pointers pointers to members classes enumerations or from other Array declaration cppreference. Solution 1 memset The fastest way to set all elements of an array to 0 is C is to use memset function which is defined in string header file memset is an intrinsic so the compiler will convert it to assembly instructions directly making its use highly optimal memset array 0 sizeof array OR memset array 0 N sizeof array By definition default initialization is the initialization that occurs when no other initialization is specified the C language guarantees you that any object for which you do not provide an explicit initializer will be default initialized C 11 8 5 11 That includes objects of type std array T N and T N
