第一个for循环在里面写int i=0;第二个for循环写i=0 突然发现第二个循环报错了，原来是只在循环内部...
(1) int i=1是定义一个变量,并赋值 (2) int i(1)就是用对象初始化的形式定义一个变量 对于 c内部类型来说没什么本质区别 对于其他的对象的定义来说应该用形式(2),因为这样减少了一步赋值的操作
int i=1”与“int i(1)”是相同，都表示对i进行初始化；int i(1)是老版本的格式
n是i的初始值，1是终止值，-1是步长。这个是冒号表达式，i=m-2:-1:1的意思是i从m-2开始，每一次减小1，一直减小到1为止。int i;for(i=0; i<3; i++)。这个语句有错误，1本身是个数字没法再赋值。 写成S1=size(x,2),还差不多，假设这里x是一个3*4的矩阵，那么size(x,2)得出的是...
区别在于后者的i结束循环仍然可用。从代码清晰的角度来讲，一个变量如果不用了就应该消失。如果不需要...
Java中int是32,范围是-2147483648到2147483647 所以i+1 i是会出现的。 int i=(int) Math.pow(2, 32); System.out.println(i); if(i+1j){ System.out.println(j-1); System.out.
这是C语言中的一种定义变量和赋值的方法,表示对i定义为整型变量,并且将1作为i的初值
