What is the difference between i++ & ++i in a for loop?

I've just started learning Java and now I'm into for loop statements. I don't understand how ++i and i++ works in a for-loop. How do they work in mathematics operations like addition and subtraction?

若已知int i=8,j=10,m,n;请写出执行如下语句m=++i;n=j--;后变量i,j.m.n的值

解析:m=++i,表示先给i加1,再赋值给m,则这个表达式计算完后,m和i都为9, n=j--,表示先赋值给n,后对j减1,计算完后,n=10,j=9;

{int i,j,m,n; i=8; j=10; m=++i; n=j++; printf ("%d,%d,%d,%d\n",i,j,i++ ...

就是前置++和后置++的区别,前置是本身的值也变,传递出的值也变,后置是本身的值不变化,但是传递出去的值是+1后的一份 ...

试分析下面程序段的时间复杂度。for (i=0; i<n; i++) for (j=0; j<m; j++) a [i] [j]=0;答案:O ...

文章浏览阅读6.8k次,点赞2次,收藏3次。 该程序段包含两层嵌套循环,外层循环变量i从0到n-1,内层循环变量j从0到m-1。 在每次内部循环中,执行语句a [i] [j]=0,因此这个操作总共执行了m*n次,故时间复杂度为O (m*n)。

Which of the following loops produces the output? 1 2 3 4 1 2 3 1 (I) for (int i = 5; i>0; i--) { for (int j = 1; j <5 j++) System.out.print (j + " "); System.out ...

# include main () { int i=010 , j = 10; printf ("%d,%d\n",+ +i , j ...

原因是:010是8进制,换算成十进制就是8,也就是i的值为8,++i后,i的值为9,所以输出9。 j--会先输出j的值,然后在做--操作,所以输出10.

java练习题求解、下列语句序列执行后,k 的值是.int x=6,y=10,k=5; switch ( x%y ) { case 0:k=x ...

解释下:x%y是整除取余数,所以switch (x%y)相当于switch (6) 然后再找6 得K=0但是后面没有break不能跳出,继续后面的语句 直到default 前面没有改变x y的值,所以直接后最后一条,default k=6*10 -6 =54 所以最后K的值是 54
