Question

NEED SAMPLE AND BASIC C-- OR C++ PROGRAMMING EXCUTION The angle in the diagram below can test to detemine if it is less then 90degree through the following equation to show that it is an acute triangle: a^2 + b^2 - c^2 > 0 where c is the length of longest side of the triangle Write a C-- program or devc++ that reads in a, b, and c; and verifies that it is an acute triangle. If c is less than the other two dimensions, or if any of a,b, and c are not positive c is greater than a+b so a triangle can?t be formed, your program should output a message instead of outputting a result . Otherwise your program should output a message stating whether the triangle is acute or not. Your program does not need to loop, i.e. it reads in and processes one set of values and then stops. Note: a=6, b=8, c=9 is an example of an acute triangle that you can use.

Explanation / Answer

Here you go :)

commnet if you have any doubts

#include <iostream>

using namespace std;

int main()
{
double a,b,c;
cout << "Enter a b c values" << endl;
cin >> a>> b>>c;
if((c<a && c<b) || (a<=0 || b<=0||c<=0) || c>a+b)
{
cout<<"Error!! invalid inputs"<<endl;
}
else
{
if(a*a +b*b -c*c >0)cout<<"Given triangle is an Acute"<<endl;
else cout<<"Given triangle is an Obtuse"<<endl;
}
return 0;
}
