WebA u prefix means unsigned. The number is the number of bits used. There's 8 bits to the byte. The _t means it's a typedef. So a uint8_t is an unsigned 8 bit value, so it takes 1 byte. A uint16_t is an unsigned 16 bit value, so it takes 2 bytes (16/8 = 2) The only fuzzy one is int.

WebJul 27, 2015 · Some people prefer to use size_t everywhere instead of unsigned int, because size_t is defined to be the return type of the 'sizeof' operator. A consequence of this is that the size_t type should be compatible as an array index for any array, whereas an unsigned int might not be. Conclusion WebJun 15, 2024 · In the C programming language, the keyword ‘int’ is used in a type declaration to give a variable an integer type. However, the fact that the type represents integers does not mean it can represent all integers. The size of an int variable is fixed and determined by the C implementation you use.
