//1*10*100*1000*10000。..的c语言程序怎么写
//至少有两种思路，一种是写个大数类，再直接算乘法
//二是偷个懒，计算结果会有几个0，直接输出结果
//1*10*100*1000*10000*。*1(n-1个0)
//0 1 2 3 4 。。。 n-1
//类加，即结果会有 （1+n-1）*(n-1)/2个0
//下面采用第二种方法
int main()
{
int n,i=1;
int k=0;
scanf("%d",&n);
k=n*(n-1)/2;
printf("1");
while(i<=k){
printf("0");
++i;
}
printf("\n");
return 0;
}
2.写一个程序关于求1到1000各位数字之和为15的数
用python 写的：
def main():
count = [x for x in range(1001)]
for num in count:
if getSum(num) == 15:
print num
#数字所有位之和
def getSum(num):
sum = 0
while num != 0:
a = num % 10
num = num / 10
sum += a
return sum
if __name__ == '__main__':
main()
更为合理的写法：
def main():
print filter(getNum, range(1001))
#是否满足条件
def getNum(num):
if getSum(num) == 15:
return num
#数字所有位之和
def getSum(num):
sum = 0
while num != 0:
a = num % 10
num = num / 10
sum += a
return sum
if __name__ == '__main__':
main()
3.c编程中怎么写1到1000所有的质数相加的和
#include <stdio.h>
main()
{
int s=0,i,j,temp=0;
for(i=2;i<1000;i++)
{
for(j=2;j<i;j++)
{
if(i%j==0)
{
temp=1;
break;
}
}
if(temp==0)
{
s+=i;
}
temp=0;
}
printf("%d",s);
}你试试。
我用10以内的质数算了下，是正确的。
4.编写个从1加到1000的JAVA程序
这种方法实用一些。
public class 递归 {
static int way(int N){
int s=0;
if(N>=1)s=N+way(N-1);
return s;
}
public static void main(String[]arg){
int NUM=1000；//定义最大的数
System.out.println(way(NUM));
}
}

6.写一个程序关于求1到1000各位数字之和为15的数
用python 写的： def main(): count = [x for x in range(1001)] for num in count: if getSum(num) == 15: print num#数字所有位之和def getSum(num): sum = 0 while num != 0: a = num % 10 num = num / 10 sum += a return sumif __name__ == '__main__': main（) 更为合理的写法： def main(): print filter(getNum, range(1001)）#是否满足条件def getNum(num): if getSum(num) == 15: return num#数字所有位之和def getSum(num): sum = 0 while num != 0: a = num % 10 num = num / 10 sum += a return sumif __name__ == '__main__': main()。
7.编写一个程序计算出1到1000为3位数的所有数之和
public class TestSum {
public static void main(String[] args) {
int sum = 0;
for(int i=1;i<=1000;i++){
if(i%3==0){
sum += i;
}
}
System.out.println("1到1000为3的倍数的所有数之和="+sum);
}
}
