初学C++,打算用博客记录学习的足迹.写了两个求质数的程序,修修改改. #include <iostream> #include <math.h> using namespace std; int main(){ int m, n, k, i, j, h; n = ; //n不应该定义在外循环内,否则无法实现换行作用 cin >> m; //开始时我将k定义在循环体外,导致结果失败,因为每个内循环结束后k值会发生改变,需要在外循环中重复定义 ; i <= m ;

Description Write a program which reads an integer n and prints the number of prime numbers which are less than or equal to n. A prime number is a natural number which has exactly two distinct natural number divisors: 1 and itself. For example, the f
总结:函数 Math.pow(x,0.5); package com.badu; import java.util.Scanner; // 输入一个数,并计算出平方根 public class AA { public static void main(String[] args) { Scanner c = new Scanner(System.in); System.out.println("请输入一个数----"); double z = c.nextInt(); double y
题目:输入3个数a,b,c,按大小顺序输出 package com.li.FiftyAlgorthm; import java.util.Scanner; /** * 题目:输入3个数a,b,c,按大小顺序输出. * @author yejin */ public class Compare { public static void main(String[] args) { Scanner s = new Scanner(System.in); int a = s.nextInt(); int
题:输入三个数a,b,n,输出a和b不大于n的公倍数的所有个数. 这题的思想是先求得a和b的最大公约数,然后用a和b的积除以最大公约数,得到最小公倍数,再持续加上最小公倍数,直到超过n,记下n的个数.如:8,12,100,最大公约数为4,则最小公倍数为24.则公倍数为:24.48.72.96,即总共有4个. 代码如下: #include<iostream> #include<algorithm> using namespace std; int main() { int a, b,
题目:输入3个数a,b,c,按大小顺序输出 public class _034Sorting { public static void main(String[] args) { sorting(); } private static void sorting() { Scanner scanner = new Scanner(System.in); System.out.println("请输入3个整数:"); int a = scanner.nextInt(); int b = s
#输入2个数,比较大小后,从小到大升序打印 a = input('first: ') b = input('second: ') if a > b: print(b,a) else: print(a,b) python没有三目运算符,但提供了三元表达式. #输入2个数,比较大小后,从小到大升序打印 a = input('first: ') b = input('second: ') print(b,a) if a>b else print(a,b)
总结:我暂时不能理解,C语言时讲过,java里就不理解了 package com.a; import java.sql.Date; import java.util.Scanner; //输入三个数,按从小到达的顺序输出 public class Test { public static void main(String[] args) { Scanner c = new Scanner(System.in); System.out.println("请输入3个数"); int a =
