$1.$ Write a C$++$ program that does the following:

a$.$ Create a C$++$ file with the name problem$2.$cpp$.$

b$.$ Prompt the user to enter three angle values in degrees.

c$.$ Checks and prints whether the three given angles form a triangle. $$If the three angles add up to $180,$ then they form a triangle.

d$.$ If the three given angles form a triangle, then the program determines and prints whether the triangle is equilateral, right, or neither.

e$.$ An equilateral triangle has three $60-$degree angles.

f$.$ A right triangle has one $90-$degree angle.

Sample run of the program:

Enter an angle in degrees: $45$

Enter an angle in degrees: $45$

Enter an angle in degrees: $90$

Can form a triangle from these angles.

The triangle is a right triangle.

Sample run of the program:

Enter an angle in degrees: $50$

Enter an angle in degrees: $70$

Enter an angle in degrees: $60$

Can form a triangle from these angles.

The triangle is neither equilateral nor right.

Sample run of the program:

Enter an angle in degrees: $10$

Enter an angle in degrees: $20$

Enter an angle in degrees: $30$

Cannot form a triangle from these angles.
