Final answer:
The given statement, 'sum += *array++;' in C++, assigns the dereferenced pointer's value to the sum and then increments the pointer's address.
Step-by-step explanation:
The given statement, sum += *array++; in C++, is valid code that combines several operators. Here's what each part of the statement does:
- array++: This increment operator increases the pointer's address by one.
- *array: The dereference operator retrieves the value at the memory address pointed to by 'array'.
- +=: This compound assignment operator adds the value on the right side to the sum on the left side and updates the sum.
Therefore, the given statement sum += *array++; assigns the dereferenced pointer's value to the sum and then increments the pointer's address.
