Answer 1

With the aid of pointer-based arithmetic operations and the usage of pointers in comparison operations, address arithmetic is a technique for determining the address of an object. Pointer arithmetic is another name for address arithmetic.

The pointers can be used for mathematical operations like addition, subtraction, etc. The outcome of an arithmetic operation on the pointer, however, will likewise be a pointer if the other operand is of type integer because we know that the pointer includes the address. These operations are addition and subtraction. In C++, a pointer's value can be increased or decreased. It signifies that we can change the pointer's value by adding or removing integer values. A pointer arithmetic can be subtracted (or added) from another in a manner similar to this.
