Need help on following program using c language Write a recu

Need help on following program using c++ language.

Write a recursive function that takes as a parameter a nonnegative integer and generates the following pattern of stars. If the nonnegative integer is 4, then the pattern generated is:

Also, write a program that prompts the user to enter the number of lines in the pattern and uses the recursive function to generate the pattern. For example, specifying 4 as the number of lines generates the above pattern.

Solution

#include <iostream>

using namespace std;

void Stars(int num,int i)
{
if (i == num)
{
return;
}
for (int j = num ;j > i; j--)
{
cout << \"*\";
}
cout << endl;

Stars(num,i+1);
for (int j = num; j > i; j--)
{
cout << \"*\";
}
cout << endl;
}

int main()
{
cout<<\"Enter number \"<<endl;
int n;
cin>>n;

Stars(n+1,1);

return 0;
}
