Pointer arithmetic allows arithmetic operations on pointers in C, such as addition and subtraction. However, since pointers store addresses, performing arithmetic operations with integer types will result in a pointer. When subtracting one pointer from another, the result will be an integer value. In C, you can perform the following arithmetic operations on pointers: Increment … Read more
