    What is the Pointers in C++?


  • #53345

    C++ enables you to have a pointer on a pointer, etc. Passing an argument by reference or by address both empower the passed argument to be changed in the calling function by the called function.

    C++ enables a function to restore a pointer to a local variable, static variable and progressively allotted memory also.

    1) Pointes is a special type of variables that are utilized to store the memory address of other variables.

    2) Pointers are pronounced ordinarily as different variables with a distinction of ‘*’ that is available before the pointer identifier.

    3) There are two operators that are utilized with the pointers one is ‘&’ and another one is ‘*’.

    4) ‘&’ is known as the address of the operator and ‘*’ is known as dereferencing operator, both are prefixed, unary operators.
