Answer 1

The given code was not correct. Below is the corrected code along with comments for each line:

using namespace std;

	int Flag=0;	//Declare a Flag to give 1 if the sides are of a right angle triangle else 0
    if(c*c == (a*a+b*b))	//Check if Pythagorous theorm appliues to sides to one combination of a, b and c
	{
		AC = c;				// Confirm for Hypotenous
		AB = a;				// Confirm for Base	
		BC = b;				// Confirm for Perpendicular	
		Flag=1;				// Right Angle triangle confirm flag
    }
