数组实验课练习题.ppt

1、程序设计 1、生成一个一维数组(10个数组元素依次为：15、23、72、43、96、23、3、65、88、17)，写程序求出这个数组中的最大值、最小值和平均值，并输出在窗体上。将最大值，最小值，平均值分别存入变量Max,Min,Aver中,平均值保留整数部分。 、求二维数组中最大元素及其所在的行和列并将最大值存入变量Max中，将最大值的行位置存入row中，列位置存入变量column中。 3、在窗体上打印数列2/1，3/2，5/3，8/5,13/8的前10项和，将和保存在变量s中。 、求3行3列的矩阵主对角线元素和副对角线之和。,编程：在窗体上打印数列2/1，3/2，5/3，8/5,13/8的前

2、10项和，将和保存在变量s中。,Private Sub Form_Click() Dim f(1 To 11) As Long f(1) = 1 f(2) = 2 :s=2 print cstr(f(2) Next i Print x = InputBox(请输入要插入的整数) *SPACE* 【?】 i = 8 Do While a(i) x *SPACE* 【?】 i = i - 1 Loop *SPACE* If i 0 Then 【?】 Else a(1) = x For i = 1 To 9 Print a(i); Next i End Sub,、本程序用于实现：从键盘接收一数字，判

3、断其是否在数组中，如果在数组中则将其删除，否则显示该数字不在数组中。 Private Sub Form_Click() Dim a(10) As Integer, x As Integer For i = 1 To 10 a(i) = Int(Rnd * 90) + 10 : Print a(i); Next i x = InputBox(请输入要删除的整数) For i = 1 To 10 *SPACE* If a(i) = x Then 【?】 Next i *SPACE* If 【?】 Then For k = i To 9 *SPACE* 【?】 Next k Print 删除后的数组

4、: For i = 1 To 9 Print a(i); Next i Else : Print 该数字不在数组中 End If End Sub,、下面的程序段用于删除数组中指定位置的数字，如果位置错误给出提示，否则分别显示删除前后的数组元素 Private Sub Form_Click() Dim a(10) As Integer, x As Integer Dim i as integer,k as integer For i = 1 To 10 a(i) = Int(Rnd * 90) + 10 Print a(i); Next i Print x = InputBox(请输入要删除第几

5、位数字) *FOUND* If x 0 Then For k = x+1 To 10 *FOUND* a(k+1) = a(k ) Next k Print 删除后的数组: For i = 1 To 9 Print a(i); Next i *FOUND* End If Print 删除位置错误 End If End Sub,、下面程序运行后单击窗体，输出结果为1234。 Private Sub Form_Click() Dim a a = Array(1, 2, 3, 4) j = 1 *SPACE* For i = 【?】 s = s + a(i) * j *SPACE* j = 【?】

6、Next i *SPACE* Print 【?】 End Sub,、题目：以下程序段用于输出杨辉三角： 1 1 1 1 2 1 1 3 3 1 1 4 6 4 1 1 5 10 10 5 1 1 6 15 20 15 6 1 1 7 21 35 35 21 7 1 1 8 28 56 70 56 28 8 1 ,Private Sub Form_Click() Const n = 10 Dim arr(n, n) As Integer For I = 1 To n arr(I, I) = 1 *SPACE* 【?】 Next I For I = 3 To n For j = 2 To I -

7、1 *SPACE* arr(i, j) =【?】 Next j Next I For I = 1 To n For j = 1 To I *SPACE* 【?】 Next j Print Next I End Sub,、编程求一个m*n矩阵中最大元素及其所在的行列号。 Private Sub Form_Click() Dim A() As Integer, max As Integer Dim M As Integer, N As Integer Dim i As Integer, j As Integer Dim col As Integer, row As Integer M = Inpu

8、tBox(输入矩阵的行数：) N = InputBox(输入矩阵的列数：) ReDim A(M, N) As Integer For i = 1 To M For j = 1 To N A(i, j) = InputBox( 输入数组元素:) Next j Next i,*FOUND* max = A(0, 0) For i = 1 To M For j = 1 To N If max A(i, j) Then max = A(i, j) *FOUND* row = j *FOUND* col = i End If Next j Next i Print Print 该矩阵元素的最大值:; m
