An array is a data structure that contains a group of elements. Typically these elements are all of the same data type, such as an integer or string. Arrays are commonly used in computer programs to organize data so that a related set of values can be easily sorted or searched.

The C library function char *strncpy(char *dest, const char *src, size_t n) copies up to n characters from the string pointed to, by src to dest.

The C library function void *memcpy(void *dest, const void *src, size_t n) copies n characters from memory area src to memory area dest.

SystemVerilog arrays can be either packed or unpacked. Packed array refers to dimensions declared after the type and before the data identifier name. Unpacked array refers to the dimensions declared after the data identifier name.

Indexing is counted from 0 to N-1 where N is size() of list. Exactly as arrays in all C-like languages. The indexes start from 0.

note the [undefined x 1] for the sparse array. Since you deleted an element, it follows that: If you delete an element from an array, the array becomes sparse.

There is a basic difference between an array and pointer is that an array is a collection of variables of a similar data type. In contrast, the pointer is a variable which is used for storing the address of another variable. ... On the contrary, the pointers can be used for allocating the memory dynamically.

void* memcpy( void* dest, const void* src,size_t count ); The memcpy() function takes three arguments: dest, src and count. This function when called, copies count bytes from the memory location pointed to by src to the memory location pointed to by dest.

char ZEROARRAY[1024]; at global scope it will be all zeros at runtime. But actually there is a shorthand syntax if you had a local array. If an array is partially initialized, elements that are not initialized receive the value 0 of the appropriate type.

When you apply it to an array the language implicitly converts the array into a pointer to the array's first element. ... So arrays really are a contiguous set of elements in memory where each element really is the value, not a pointer to another location containing the value.

A structure may contain elements of different data types – int, char, float, double, etc. It may also contain an array as its member. Such an array is called an array within a structure. An array within a structure is a member of the structure and can be accessed just as we access other elements of the structure.

An array is a collection of elements of a similar data type. Linked List is an ordered collection of elements of the same type in which each element is connected to the next using pointers. Array elements can be accessed randomly using the array index. Random accessing is not possible in linked lists.
