Can you give me the key to solve this:

Question

you will be given three values a,b,c lengths of the sides of a triangle -->>> you should output if they can built a triangle or not //B-)

Answer 1

Read this:
https://en.wikipedia.org/wiki/Triangle_inequality

The triangle inequality theorem states that the sum of the side lengths of any 2 sides of a triangle must exceed the length of the third side.

int a = 15, b = 36, c = 50;

std::cout << std::boolalpha
<< (a + b > c &&
a + c > b &&
b + c > a)
<< std::endl;

Answer 2
