What are the sizes of each primitive datatype on a Metro M4 Express SAMD51? What are the data sizes of all the primitive datatypes on a Metro M4 Express SAMD51 C++ implementation? In some C++ implementations, int has 16 bits and in other implementations it has 32 bits. Is
And that is the only difference in fundamental type sizes. On 8-bit Arduinos int is 16 bit and on 32-bit int is 32 bit.


short is 16 bit
long is 32 bit 
long long is 64 bit
