WebJan 5, 2024 · The number of bytes required for saving all the values are $\lceil4 + 3 \times 100 / 8\rceil = 42$. Note that $4$ is a uint32_t value indicating the number of valid bits in the binary file. If we save all the unsigned integers as uint8_t values, each value will take $1$ byte, i.e., $8$ bits, and we don’t need an additional value to indicate ... WebIf check is successful you would delete (or free) copied part and change values in buffer however you wish, then copy all data from buffer into your array (or vector) and delete heap allocated memory. Converting bitset or any other data type to array is done either by populating an passed by reference array or by union.
