A triangle is classified by the relationship between its three sides: Equilateral — all three sides are equal (all angles are 60°) Isosceles — exactly two sides are equal (two base angles are equal) Scalene — all three sides are different (all angles are different) Before classifying, the program validates the triangle inequality: for any …
The area of an isosceles triangle in C is computed using the Pythagorean theorem: given the base and the length of the two equal sides, you drop a perpendicular from the apex to the midpoint of the base, splitting the triangle into two right triangles. The height h = sqrt(side² − (base/2)²), and the area …
Writing a Hello World program in C without using a semicolon is a classic interview trick and a fun way to understand how C evaluates expressions. In C, every statement ends with a semicolon — but you can embed a function call inside the condition of if, while, or switch statements, which do not require …
