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.
#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; }
I am very interested in the cpp courses
Please help me more
