Question

C++ programming:

Paula and Danny want to plant evergreen trees along the back side of their yard. they do not want to have excessive number of trees. write a program that prompts that the user to put the following:

the length of the yard.

the radius of a fully grown tree.

the required space between fully grown trees.

the program outputs the number of trees that can be planted in the yard and the total space that will be occupied by the fully grown trees.

Answer 1

C ++ code for the above question is below : -

#include <iostream>

using namespace std;

int main()
{
int length,radius,space; //varirable declarations
cout<<"enter the length of the yard: ";
cin>>length; //getting length of the yard as input from user
cout<<"enter the radius of a fully grown tree: ";
cin>>radius; //getting the radius of fully grown tree from user
cout<<"enter the required space between fully grown trees: ";
cin>>space; //getting the space between trees from user
  
// the number of trees that can be planted in the yard and
// the total space that will be occupied by the fully grown trees.
  
int number_of_trees = length/(2*radius + space ); //number of trees which can be planted in yard
cout<<"The number of trees that can be planted in the yard are : "<<number_of_trees<<endl;
// space occupied by trees will be equal to their diameter * number of trees
cout<<"The total space that will be occupied by the fully grown trees : "<< number_of_trees*(2*radius)<<endl;
  
return 0;
}
