Did I correctly do this function? Did I correctly do the precondition and postcondition?
//Precondition: flag_position is a non-negative integer and hBit_flags is a handle to a valid Bit_flags object.
//Postcondition: returns the value of the flag at index flag_position if it is in bounds or -1 otherwise.
int bit_flags_check_flag(BIT_FLAGS hBit_flags, int flag_position){
Bit_flags* pBit_flags = (Bit_flags*)hBit_flags;
int i = flag_position / 32;
flag_position %= 32;
return ((1 << flag_position) & (pBit_flags->data[i])) != 0;
if (flag_position <= pBit_flags->capacity) {
return *pBit_flags->data;
}
else{
return -1;
}
