问题:输入一个整数,计算它各位上数字的和 Scanner sc = new Scanner(System.in); int a = sc.nextInt(); int sum = 0; while(a!=0){ sum = sum+a%10; a=(int)a/10; } System.out.println(sum);
#include <iostream> #include <algorithm> #include <vector> using namespace std; int f(int n, int m) { n = n % m; cout<<n<<endl; vector<int> v; for(;;) { v.push_back(n); n *= ; cout<<n<<endl; n = n % m; cout&
package nothh; public class mmm { public static void main(String[] args) { // TODO Auto-generated method stub //相比起阶乘之和,阶乘的倒数和就需要用到float或者是double. float x = 0; float y = 0; int z = 20; while(z>0) { x = z; for(int j = z - 1; j > 0; j--) { x = j * x;

package four; public class fouronetwo { public static void main(String args[]){ double sum = 0,a = 1; int i = 1; while(i <= 20) { sum = sum+a; i = i+1; a = a*(1.0/i); } System.out.println(sum); } } 解释:当i=1, sum=1, i=2, a=1*(1/2); 当i=2, sum=1+1*1/2, i
