Question

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

Answer 1

Answer:

The code for development of this kind of arrowhead and arrow body as given in example is as below.

Explanation:

Assumptions

• Assuming the language required is C++. As the basic outlook is similar, the syntax of specific language can be varied.
• Here 1 is used as the second digit in example. It can be replaced with any other digit depending on the input from the user.
• The concept of function is used which will be called back whenever required.

The basic definition of the code is such that the essential number of spaces, zeros and ones are estimated accurately

Code

#include<iostream>

using namespace std;

//Defining the function as arrow with inputs as x and y integer with no output.

void arrow(int x, int y);

int main() //main function where the main code is present.

{  

  //So variables are initialized

  int x,y;

  //get input from the user via keyboard.

  cout<<"Enter Two Integers: \n";

  cin>>x>>y; //storing integers as x and y.

  //Displaying extra line at command window to get clear figure of arrow

  cout<<"\n\n\n\n";

  //Calling function to draw arrow

  arrow(x,y);

  return 0;

}

void arrow(int x, int y)

{  

  //1st line has  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;

}
