A reference to the first element in the list container. If the list object is const-qualified, the function returns a const_reference. Otherwise, it returns a reference. Member types reference and const_reference are the reference types to the elements of the container (see list member types ). Example Edit & run on cpp.sh Output: C++ List is a STL container that stores elements randomly in unrelated locations. To maintain sequential ordering, every list element includes two links: one that points to the previous element; another that points to the next element; C++ STL list implementation.

Be careful when counting with negative indices: they do not start from 0. -0 is equivalent to 0, the first list elem The list front is a built in function in C STL which is used to return a reference to the first element in a list container Unlike the list begin function this function returns a direct reference to the first element in the list container Syntax list name front Parameters
