Inside the loop() function, we use the sizeof() function to determine the total number of bytes required to store the myArray array. We divide this value by the number of bytes required to store a single element of the array (which is given by sizeof(myArray[0])) to get the lengt...

②:Array,如果1.传的参数是数字,数字决定数组的长度,会用empty来填补空位 2.传的参数不是数字,就是数组项 二:检测数组类型 只要是对象,就是引用数据类型,操作的就是内存地址。 把arr的内存地址赋值给b,此时b与arr都可以操作【1,2,3】,且互相影响, ...
