代码如下所示：

复制代码 代码如下:

#include "stdafx.h"

#include <iostream>

#include <math.h>

bool IsSushu(int n)

{

bool IsSushuFlg = true;

if( n <= 1)

{

return false;

}

for( int i = 2; i <= (int)sqrt((double)n); i++ )

{

if( 0 == n % i )

{

IsSushuFlg = false;

break;

}

}

return IsSushuFlg;

}

#define N 1000

int main()

{

printf("Su shu is: /n");

for( int i = 2; i < N; i++)

{

bool IsSushuFlg = IsSushu(i);

if( IsSushuFlg )

{

printf("%d /n", i);

}

}

system("pause");

return 0;
