1.数学知识 求三角形的面积 三边的边长分别为:a, b, c; 公式:s = (a + b + c) / 2; area = √s * ( s - a) * (s - b) * (s -c); 2.源代码 #include<iostream> #include<cmath> using namespace std; bool TriangleArea(double a, double b, double c, double &area) { if(a + b <=
原题描述 Given n non-negative integers representing the histogram’s bar height where the width of each bar is 1, find the area of largest rectangle in the histogram. Above is a histogram where width of each bar is 1, given height = [2,1,5,6,2,3]. The lar
任给三条边长,判断能否构成三角形,如果能,求出其面积和周长 程序: #include<stdio.h> #include<math.h> int main() { double a, b, c, d, s, area; printf("请输入三个正数:"); scanf("%lf%lf%lf",&a,&b,&c); if ((a + b > c) && (a + c > b) &&a
