编写程序,实现随机生成一个3位的整数n,将n中的三...

#include#include#includeint main(){ srand((unsigned int)time(null)); int n=rand()%900+100; int m=n%10*100+n/10%10*10+n/100%10; printf("%d\n",m); return 0;}

使用 Random类 可以实现。 Private Sub Button1_Click(sender As Object, e As EventArgs)_Handles Button1.ClickDim newrandom1 As New RandomDim newrandom2 As New RandomTextbox1.text() = newrandom1.next(100,999)Textbox2.text() = newra...

Private Sub Command1_Click() Dim Plate As Integer Dim a(3) As Integer Randomize Plate = Val(Text1.Text) - 1 For i = 1 To 3 a(i) = Int(Rnd() * Plate + 1) Next Label1.Caption = a(1) Label2.Caption = a(2) Label3.Caption = a(3) End...

#include const int MAXSIZE = 100;int main() {int i,j,t,n,N,a[MAXSIZE];scanf("%d",&N);while(N--) {scanf("%d",&n);for(i = 0; i < n && i < MAXSIZE; ++i)scanf("%d",&a[i]);for(i = 0; i < n - 1; ++i) {for(j = i + 1; j < n; ++j) {if(a...

要计算出平均值,但是不显示小数么? #includeint main(){int a[8][8],i,j,sum;float aver;//用float来显示可以显示出小数for(i=0;i

Dim n As Long, i As Long, j As Long, s As String Dim a() As Long Randomize n = Int(Rnd * 80 + 20) ReDim a(n - 1) For i = 0 To n - 1 Randomize a(i) = Int(Rnd * 100) Next m = 0 Me.Show For i = 0 To n \ 10 s = "" For j = 0 To 9 If...

Int(n+Rnd*(m-n+1))产生n,m区间内的随机整数 Mid(字符串,n,m)n是起始位置,m是长度,这里m取1 输入用n=Inputbox(提示文字,标题文字,预留值) m=Inputbox(提示文字,标题文字,预留值) 输出用Msgbox(提示文字“这里提示文字就是输出的字符串",...

public class Demo {public static void main(String[] args) {Random random = new Random();int n = random.nextInt(40) + 10;System.out.println("随机产生" + n + "个,0-100之间的随机整数如下:");for (int i = 0; i < n; i++) {System.ou...

前几天刚刚做了,呵呵 #include using namespace std; //返回杨辉三角第x行第y列的值,起始行为第0行 int SanJiaoYang(int x,int y); int main() { int RowCount,i,j,k; cout > RowCount) { for(i = 0;i < RowCount;++i) { for(j = 1;j < RowCou...

比如123 n/100*100 = 100 取出整百位 n-100 = 23 取出十位个位 23 / 10 =2 取出10 其实根本不用这么麻烦 123 / 10 = 12 12 % 10 = 2 直接取出十位
