The parentheses in the pointer expression *(gPtr + 3) are not necessary to access the desired array element correctly.

The parentheses are necessary because the addition operation (+) has a higher precedence than the dereference operator (*). Without parentheses, the expression would attempt to dereference `gPtr` first and then add 3 to the resulting value, which is not the intended operation. The parentheses ensure that the addition is performed first, calculating the correct address, and then the dereference operator is applied to access the array element.
