- for(int j=0;j<34;j++){
- for(int z=0;z<300;z=z+3){
- if((5*i+3*j+z/3==100)&&(i+j+z==100)){

vb.net代码:
- Module Module1
- Sub Main()
- Dim count,i,j,k As Integer
- count = 0
- For i = 0 To 20
- For j = 0 To 34
- For k = 0 To 300
- If (((5 * i) + (3 * j) + (k / 3) = 100) And (i + j + k = 100)) Then
- Console.WriteLine("母鸡:{0}" + "公鸡:{1}" + "小鸡:{2}",k)
- count = count + 1
- End If
- Next k
- Next j
- Next i
- Console.WriteLine("有{0}种方案",count)
- Console.ReadLine()
- End Sub
- End Module
