Question

a) Write a function drawShape() that accepts a parameter n, and:

• If n is odd, it constructs a pattern of a diamond of height n
• If n is even, it constructs an hourglass of length n

b) What is the time complexity of the drawShape() function you created?

C++ language with for loop

Answer 1

#include <iostream>

using namespace std;

void drawShape(){

int n;

cout<<"Enter the Parameter N"<<endl;

cin>>n;

if(n%2!=0){

cout<<"The Number you entered is ODD"<<endl;

int c, k, count=1;

count=n-1;

for (k=1; k<=n; k++)

{

  for(c=1; c<=count; c++)

  {

    cout<<" ";

  }

  count--;

  for(c=1; c<=(2*k-1); c++)

  {

    cout<<"*";

  }

  cout<<"\n";

}

count=1;

for(k=1; k<=(n-1); k++)

{

  for(c=1; c<=count; c++)

  {

    cout<<" ";

  }

  count++;

  for(c=1 ; c<=(2*(n-k)-1); c++)

  {

    cout<<"*";

  }

  cout<<"\n";

}

// getch();

}

else if(n%2==0){

cout<<"The Number you entered is EVEN"<<endl;

int i,j,k=9,s=0,l;

// clrscr();

for(i=0;i<5;i++,k-=2,s+=1)

{

for(l=s;l>=0;l--)

cout<<' ';

for(j=k;j>0;j--)

cout<<"#";

cout<<endl;

}

for(i=0;i<5;i++,k-=2,s-=1)

{

for(l=s-1;l>=0;l--)

cout<<' ';

for(j=k;j<0;j++)

cout<<"#";

cout<<endl;

}

// getch();

}

}

int main() {

drawShape();

return 0;

}

PLEASE GIVE A THUMBS UP!!!!!!!!!!!
