Can you help me to fix this code

What I see is you are missing the functions's prototypes in your code(no matter here) There is a problem with the insert_element(). Try removing it😉 ( just comment it 😁) and edit Tri_T(T, N+1) to Tri_T(T, N) I will explain it to you tomorrow, it's too late now! Have a good night!

Please add comments to your code se we can easily understand what are you doing! Thanks !

Okay

Thank you so much for the help Have a good night
