 程序代码：#include<iostream> 变量名输入不正确，学会自己从编译信息查找using namespace std; int main() {double horizleg,vertleg,area; horizleg=5.0; vertleg=7.0; area=0.5*horizleg*vertleg;int n; for(n=1;n<=10;n++) horizleg+=1.0; vertleg/=2.0; area=0.5*horizleg*vertleg; cout<<endl <<"triangle area="<<area<<endl;return 0;} |
#include<iostream>
using namespace std;
int main()
{double horizleg,vertleg,area;
horizleg=5.0;
vertleg=7.0;
area=0.5*horizleg*vertleg;int n;
for(n=1;n<=10;n++)
hovertleg+=1.0;
vertleg/=2.0;
arean=0.5*horizleg*vertleg;
cout<<endl
<<"triangle arean="<<arean<<endl;return 0;}
