If we increment the character pointer by 1 then it will point to the address which will be just 1 byte more to the current pointing address. Let us see an example where pcData is a character pointer and we performing an arithmetic operation on it.
When we increment the pcData then it points to the next character location without impacting the stored data. The size of the character is 1 byte that’s why pointer moves only 1 byte of memory. .
