Here is my question, language use here is C

Triforce Triforce is a shape consisting of three equilateral triangles, where the top triangle rests on the top corners of the other two triangles as shown below Write a program that displays a Triforce of a given size The height will be given as a line of input to your program The height should be within the range of 2 to 20 inclusive If height or missing, output invalid height then quit. nvalid arguments are on a first seen basis. First argument that is invalid is the cause of the program terminating In the event of invalid arguments the program should exit with code 1 Example 1 Enter height 2 Example 2 Enter height 3
