Introduction
C++ program to check whether a triangle can be formed by the given value for the angles. I have used DEV-C++ compiler for debugging purpose. But you can use any C programming language compiler as per your availability.
C++ program to check Triangle can be formed from angles.
#include<iostream>
using namespace std;
int main()
{
int anglea, angleb, anglec, sum;
cout << "Input three angles of triangle : ";
cin >> anglea >> angleb >> anglec;
// Calculate the sum of all angles of triangle
sum = anglea + angleb + anglec;
// Check whether sum=180 then its a valid triangle otherwise invalid triangle
if(sum == 180)
{
cout << "It is a valid triangle. "<<endl;
}
else
{
cout << "It is a invalid triangle.";
}
return 0;
}Result
Here are some more example for C++ program for practice:
