    sounds recursive, what is your current attempt like?

    It's not recursive, and technically a ball which rebounds 5% less than last time is like Zeno's arrow: It never comes to rest.

    Code:
    int main() {
    	float h = 100.0f;
    	int i = 1;
    	while (h>0.0f) {
    		h -= h*0.05;
    		cout << i++ << ":" << h <<endl;
    	}
    	return 0;
    }

    Flow chart? Haven't used on or created one in years - actually since my high school BASIC class.

    I prefer UML and sequence diagrams to some clunky flow chart.

    Theoretically yes, practically no because there are limits to all computer numbers!

    ball rebouncing problem

    actually my question is
    " ball is dropped from height h i it rebounds 5%less to its previous rebound after how many rebounds the ball will come to rest. "
    in this problem word "rest " is mentioned here so there should b rest in the end

    Okay, perhaps we can alter reality to better suit your assignment.

    Altho, has Cipher says, computer numbers are not infinitely regressive, so eventually you will reach a height which does not change. However, that will not be zero.

    So you need to decide whether a non-zero height can be close enough to "at rest", or what. I guess hovering a billionth of a unit off the ground is more or less at rest.
