Question

1.13 LAB: Input and formatted output: Right-facing arrow

Given two input integers for an arrowhead and arrow body, print a right-facing arrow.

Ex: If the input is:

0 1

the output is:

     1
     11
00000111
000001111
00000111
     11
     1

Can anyone help me with this? I was able to get the smaller arrow on Chegg but not this one. Thank You!

Answer 1

Assumptions :

• Considering C++ as programing language as there is no information regarding programming language used.
• Considering Second no( here it's 1), which has been given as input should be at Arrowhead.

I have written a function for drawing an arrow. The concept is very simple which could be used in any language.

CONCEPT:

From the observation of the output:

• First, second, sixth, and seventh line has 2 spaces.
• Third, Fourth and Fifth line has individually 5 Zeroes.

We just need to print individual lines based on these observations to get the desired output. We could simply print these things as there is no requirement of changing length of the arrow.

CODE:

#include<iostream>

using namespace std;
//function defination for drawing right facing arrow
void draw_arrow(int x, int y);
int main()
{  
   //initializing Variables
   int x,y;
   //get input
   cout<<"Enter Two Integers: \n";
   cin>>x>>y;
   //Displaying extra line at command window to get clear figure of arrow
   cout<<"\n\n\n\n";
   //Calling Function to draw arrow
   draw_arrow(x,y);
   return 0;
}

void draw_arrow(int x, int y)
{  
   //1st line -- 2 spaces and 1 second input number
   cout<<" "<<" "<<y<<endl;
   //2nd line -- 2 spaces and 2 second input number
   cout<<" "<<" "<<y<<y<<endl;
   //3rd line -- 5 first input and 3 second input number
   cout<<x<<x<<x<<x<<x<<y<<y<<y<<endl;
   //4th line -- 5 first input and 4 second input number
   cout<<x<<x<<x<<x<<x<<y<<y<<y<<y<<endl;
   //5th line -- 5 first input and 3 second input number
   cout<<x<<x<<x<<x<<x<<y<<y<<y<<endl;
   //6th line -- 2 spaces and 2 second input number
   cout<<" "<<" "<<y<<y<<endl;
   //7th line -- 2 spaces 1 second input number
   cout<<" "<<" "<<x<<endl;
}
