Check validity of a triangle


Write a program to check whether a triangle is valid or not, when the three angles of the triangle are entered by the user. A triangle is valid if the sum of all the three angles is equal to 180 degrees. Test Case 1 Input (stdin) 60 60 60 Expected Output Triangle is valid Test Case 2 Input (stdin) 60 50 56 Expected Output Triangle is not valid

Program :

#include <iostream>
using namespace std;
int main()
  int a,b,c;
  if( a == b)
    cout<<"Triangle is valid";
    cout<<"Triangle is not valid";
 return 0;
