WebAug 21, 2014 · For example, an int is defined by the C standard to be at least 16 bits. a 32-bit CPU might process 32-bit numbers efficiently, and so an int might be stored in 32 bits (or 4 bytes) for that CPU. A different CPU might only be able to process 16 bits at a time, and so it would store the number in that format instead.
C sizeof return bit or byte
Did you know?
WebIt is because the sizeof () operator returns the size of a type in bytes. You learned from the Data Types chapter that an int type is usually 4 bytes, so from the example above, 4 x 5 (4 bytes x 5 elements) = 20 bytes. To find out how many elements an array has, you have to divide the size of the array by the size of the data type it contains: WebMake the executable test_linked (the default target of the Makefile) and execute the result: make./test_linked.
