5、Eratoshenes筛选是一种寻找素数的方法，该方法表述如下：
1）创建一个一维数组，把所有的元素初始化为1（表示真），下标为素数的元素保持1不变，其它下标的元素
最终被置为0
2）从数组下标2出发，每次发现值为1的数组元素时，则看其后的所有元素，把下标是它们倍数的那些元素置
为0。例如，对下标2来说，凡是2的倍数的下标（4，6，8，10，···）都将其元素置为0，对下标3来说，
凡是否的倍数的下标（6，9，12，15，···）将其元素置为0。
当以上过程结束后，仍为1的数组元素的下标就是素数，将这些下标打印输出即可。编写程序，
用含有1000个元素的数组确定并打印出1~999之间的所有素数

程序在vc6.0下调试通过.
C语言程序编程
1.编写一个程序它的功能是;打印出1到1000之内的能被7或11整除,但不能同时被7和11整除的所有数
#includestdio.h
void main(void)
{
int i,j;
for(i=1,j=0;i1000;i++)
{
if((!(i%7)||!(i%11))(i%77))
{
printf("%d\t",i);j++;
if(!(j%8)) printf("\n");
}
}
}
2.编写一个程序其功能是;将两个数位的整数放在C中并合并的方式是;将A的十位和个位依次放在C数的百位和个位,例如;当A=45,B=15
得到的结果是C=4515
你的第2题表达不清，我按照自己的理解给你写了一个，如果不行你要把题目的意思说清楚我才能做。
#includestdio.h
void main(void)
{
int a,b,c,flag;
do{
flag=0;
printf("请输入a,b(两位整数):");
scanf("%d%d",a,b);
if(a0||b0||a100||b100)
{
flag=1;
printf("对不起，你输入错误，请重新输入.\n");
}
}while(flag==1);
c=a*100+b;
printf("c=%d\n",c);
}
3.编写一个程序其功能是;计算并输出下列多项式值;
Sn=1+1/1!+1/2!+1/3!+1/4!+........+1/n!如主函数键盘给n输入15输出为S=2.718282
#includestdio.h
int mul(int x);
void main(void)
{
double SN=1.0f;
int i,N;
scanf("%d",N);
if(N=0) printf("对不起，请确保N=1\n");
for(i=1;i=N;i++)
SN+=1.0/mul(i);
printf("SN=%lf\n",SN);
}
int mul(int x)
{
int i,y;
if(!x) return 1;
for(i=1,y=1;i=x;i++)
y*=i;
return y;
}
4.编写一个程序其功能是;判断一个数是不是回文数(所谓回文数是指,从左到右读和从右到左读是同一样的结果)如;121是回文数而
1211就不是
#includestdio.h
#includestdlib.h
void main(void)
{
int x,y;
scanf("%d",x);
if(x0)
{
printf("输入错误!\n");
exit(-1);
}
y=x;
int i,j,k;
for(i=1,k=0;x!=0;x/=10)
{
j=x%10;
k=k*10+j;
}
if(y==k) printf("%d是回文数\n",y);
else printf("%d不是回文数\n",y);
}
5.编写一个程序其功能是;完成5个数的大到小的排序.如;1,2,3,4,5输出接个是5,4,3,2,1
#includestdio.h
#includestdlib.h
void main(void)
{
int i,j,k,a[5];
i=0;
do
{
printf("请输入第%d个数:",i+1);
scanf("%d",a+i);
i++;
}while(i5);
for(i=0;i5;i++)
for(j=i;j5;j++)
{
if(a[i]a[j])
{
k=a[i];
a[i]=a[j];
a[j]=k;
}
}
for(i=0;i5;i++)
printf("%d\t",a[i]);
}
