用c++写代码：用 sizcol 操作符求出表 2-2 中各数据类型的字节长度，并按 size of char1 bytesize of int2 byte 的格式打印输出

#include <stdio.h>

int main() {
    printf("size of char: %ld byte\n", sizeof(char));
    printf("size of int: %ld bytes\n", sizeof(int));
    printf("size of float: %ld bytes\n", sizeof(float));
    printf("size of double: %ld bytes\n", sizeof(double));
    return 0;
}

输出：

size of char: 1 byte
size of int: 4 bytes
size of float: 4 bytes
size of double: 8 bytes
