c语言中怎么随机抽选100个数字并排序？

#include <stdio.h>

#include <stdlib.h>

int main()

{

int num[100]

int time=0

int numtemp

while (1) //取随机数

{

numtemp = rand()%1000

if (numtemp >= 100 &&numtemp <=999 )

{

num[time] = numtemp

time++

}

if (time == 100)

{

break

}

}

/* for(int i=0i<100i++) //冒泡排序比较方法

{

for (int j=99j>ij--)

{

int temp

if (num[j] <num[j-1])

{

temp = num[j]

num[j] = num[j-1]

num[j-1] = temp

}

}

printf("%d\n",num[i])

}*/

for (int i = 0i <100 - 1i++) //选择排序比较方法

{

int iMin = i

for (int j= ij <100j++)

{

if(num[j] <num[iMin]) iMin = j

}

if (iMin != i)

{

int nTmp = num[iMin]

num[iMin] = num[i]

num[i] = nTmp

}

}

for (int nI=0nI<100nI++)

{

printf("%d\n",num[nI])

}

return 0

}

'作者:xsfhlzh

'功能:取NumMin到NumMax间的n个随机整数

'说明:取数标志数组是Byte，每一位表示NumMin到NumMax间某个数的状态

'示例:

'a = GetRndNotRepeat(1, 10000, 2000)

'If UBound(a) >= 0 Then

'For i = 0 To 1999

'Debug.Print a(i)

'Next i

'End If

Dim arr() As Integer

If n >NumMax - NumMin + 1 Then

ReDim arr(-1 To -1)

Else

ReDim arr(n - 1)

Dim b() As Byte

m = Int((NumMax - NumMin) / 8)

ReDim b(m)

'取数标志

Dim x As Integer

Dim y As Integer

Dim z As Byte

Randomize

For i = 0 To n - 1

Do

'找到x的位置，y表示x在数组的第几个字节，z表示x在该字节的第几位

x = Int(Rnd * (NumMax - NumMin + 1)) + NumMin

y = x - NumMin

z = 2 ^ (y Mod 8)

y = y \ 8

Loop While b(y) And z

b(y) = b(y) Or z

arr(i) = x

'找到未取的数，并放入数组，设置标志位

Next i
