WebThe C++ language gives the programmer the impression that memory is laid out as a sequence of something C++ calls “bytes.”. Each of these things that the C++ language calls a byte has at least 8 bits, but might have more than 8 bits. The C++ language guarantees that a char* ( char pointers) can address individual bytes. WebDec 15, 2024 · For each bit in the value representation of the result that is indeterminate, the smallest object containing that bit has an indeterminate value; the behavior is undefined unless that object is of unsigned char or std::byte type. The result does not otherwise contain any indeterminate values.

Convert uint8_t* to char* in C++

Webuint8_t and char both are of size 8 bits. Moreover, uint8_t is a typedef for char and hence, there will be no loss in conversion if an uint8_t variable is casted to become a char. uint8_t input = 12; char input2 = (char) input; If we are dealing with an array or vector of uint8_t, the process is similar. Just cast the vector to char*.
