a.Length 和a［i].Length各是什么意思

a.Length 和a［i].Length各是什么意思 length:+a.length 还有 a[i]+ if(a[i]==a.length-1)是什么意思 一道GMAT的题目.我很无语Q11:A rectangular picture is surrounded by a boarder, as shown in the figure above. Without the boarder the length of the picture is twice its width. If the area of the boarder is 196 square inches, what is the lengt =(a.length for(i=a.length-1;i>=0;i--)怎么理解 I need ——of rope to tie all the books为什么用a length length是什么词啊用long 为什么不行 我想知道一个如下方程的根的分布,做出图形看看,结果错了,什么原因呢?方程是cos(xsin(cita))在0-pi 的积分等于0我用matlab画出它的图形 出错了cita=0:0.01:pi;m=0:0.1:pi;syms x,;y=zeros(1,length(m));for i=1:lengt 英语翻译a medium-body shiraz full of subtle,yet complex flavours derived from cooler climate terroir,short-term wood-aged prominent fruit.with a mouth full of delicate blackcurrant,aged berries&firm tannins,combine to give a delicious aged &lengt for (int i=1; i < a.Length; i++) {Console.WriteLine(a[i].ToString());改为 foreach语句,这个语句应该如何写呢? matlab新人,想把矩阵中的符号变量替换为数值变量,程序运行结果不对,程序为：x=-1:0.5:1;y=x;syms t sf=[1 t s t+s];A=zeros(length(x).*length(y),4);for n=1:length(x)*length(y); for i=1:length(x); for j=1:length(y); A(n,:)=subs( A sperm whale is________than a killer whale in its length Index and length must refer to a location within the string. Parameter name: length.这是什么意思? 求详细解释,错误在哪里int a[] = {1 , 2 , 3 , 4} ;for(int i = 0 ; i < a.length ; i++)a[i + 1] *= a ;int expr = a[3] ; length-1是什么意思!public class cy00{public static void main(String args[]){int i;int a[]=new int[5];for (i=0; i0; i--) System.out.println(a[+i+]=+a[i]);}}java的 那个i=a.length-1 为什么运行后的结果是从大到小的! matlab中 Error using ==> mtimes Inner matrix dimensions must agree.程序A=[3 8 5 1 2];B=[3 4 5 2 6];>> i=1:length(A);>> i=1:length(B);>> sum=sum(A(i)+A(i)*B(i))Error using ==> mtimesInner matrix dimensions must agree. 1/4-inch lengths in a 4- inch length MATLAB中plot([0 x1],zeros(1 ,length(A)+1),
