In the C++ programming language, a reference is a simple reference datatype that is less powerful but safer than the pointer type inherited from C.The name C++ reference may cause confusion, as in computer science a reference is a general concept datatype, with pointers and C++ references being specific reference datatype implementations.
This representation for multi-dimensional arrays is quite prevalent in C and C++ software. However, C and C++ will use a linear indexing formula for multi-dimensional arrays that are declared with compile time constant size, e.g. by int A [ 10 ][ 20 ] or int A [ m ][ n ] , instead of the traditional int ** A .
unsafe void DeclareStackBasedArrayUnsafe (int size) {int * pArray = stackalloc int [size]; pArray [0] = 123;} C# version 7.2 and later allow the array to be allocated without the "unsafe" keyword, through the use of the Span feature.
As an example consider the C declaration int anArrayName[10]; which declares a one-dimensional array of ten integers. Here, the array can store ten elements of type int. This array has indices starting from zero through nine. For example, the expressions anArrayName[0] and anArrayName[9] are the first and last elements respectively.
Identifier Description Time manipulation difftime: computes the difference in seconds between two time_t values : time: returns the current time of the system as a time_t value, number of seconds, (which is usually time since an epoch, typically the Unix epoch).

In 1990, The Annotated C++ Reference Manual was published. This work became the basis for the future standard. Later feature additions included templates, exceptions, namespaces, new casts, and a Boolean type. In 1998, C++98 was released, standardizing the language, and a minor update was released in 2003.
