The myHash call in the switch on the argument stringType may or may not be a compile time constant, depending on the context the function is called (in a constant expression or not.) … WebA uint16_t is an unsigned 16 bit value, so it takes 2 bytes (16/8 = 2) The only fuzzy one is int. That is "a signed integer value at the native size for the compiler". On an 8-bit system like the ATMega chips that is 16 bits, so 2 bytes. On 32-bit systems, like the ARM based Due, it's 32 bits, so 4 bytes.
