How to initialize array with array in C? Array initialization - java - Array initialization Initializing arrays in C is error-prone and tedious.C uses aggregate initialization to make it much safer. Java has no aggregates like C, since everything is an object in Java. It has nothing to do with whether youre initializing an object or an array. If youre initialization an object (member of an array or not) rather than a reference, and calling the copy constructor, the object being copied had better be constructed.

The answer below applies to Classic (pre-11) C.Which constructor gets called when I create an array of Fred objects? This aggregate initializes the array, which in turn default initializes each pointer. And since pointers are fundamental types, that will do zero initialization, setting them all to nullptr. This not only declares the array but initializes every element in the array to zero.

When an initialization of values is provided for an array, C allows the possibility of leaving the square brackets empty .Static arrays, and those declared directly in a namespace (outside any function), are always initialized. If no explicit initializer is specified, all the elements are The C language definition specifies that, before the main function in a C program is executed, all objects with constructors, from all the files included in the program must beYou might want to specify the initialization order of static objects declared in various files and libraries in your program. What else can be the problem? Please help.
