C Program to Find the Size of int, float, double and char
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: WebSize of int: 4 bytes Size of float: 4 bytes Size of double: 8 bytes Size of char: 1 byte.
