big O notation Complexity graph, what library should I use and wich IDE?

Question

I would very much appreciate a detailed answer to how to calculate and draw the graph of a program's complexity (c++)

Answer 1

If u wanna represent graphs there is even no need to use any library .. U can even use some logic like this to create graphs..
In the following program i had represented graphs for 3 recursion functions ..u can modify the logic for ur big o notation as the graph representing logic will be the same only recursion function need to be replaced with a big o notation finder...
