需求说明: 编写Java程序,判断输入的三条长度的边,是否能构成三角形. (三角形第三边大于两边之和小于两边之差) 实现代码: package test; import java.util.Scanner; public class test { public static void main(String[] args) { //三角形第三边大于两边之和小于两边之差 Scanner sc = new Scanner(System.in); System.out.println("请输入第一条边

描述 Given the coordinates of the vertices of a triangle,And a point. You just need to judge whether the point is in the Triangle. 输入 The input contains several test cases. For each test case, only line contains eight integer numbers , describing the c
原理: 要判断输入的三条边能否够成三角形,只需满足条件两边之和大于第三边即可. #include<stdio.h> int main() { printf("请输入三个边长:\n"); float a, b, c;//定义变量 scanf_s("%f%f%f", &a, &b, &c);//输入边长 if(a + b > c&& a + c > b&& b + c > a)//判断
package test; import java.util.Scanner; //判断输入的数是不是素数 public class Test18 { public static void main(String[] args) { Scanner s = new Scanner(System.in); System.out.println("输入判断的数"); int a = s.nextInt(); for(int i=2 ; i<=a;i++){ //最小的素数是2 if(
笨办法学python第35节 该节主要是讲分支与函数,主要遇到的问题是python中如何判断输入是数字. 首先原代码如下: from sys import exit def gold_room(): print "This room is full of gold. How much do you take?" next = raw_input("> ") " in next: how_much = int(next) else: dead(&quo
