Scratch 2050

Shape drawing is not only done in Scratch. It’s also done in other programming languages. Let’s see one of the programs that can print out a triangle in C++ programming language. Then we will show another program made in Scratch that draws the triangle too.

You will notice that a triangle drawn in Scratch is seamless shape made up of straight lines while a triangle printed out in C++ is made up of asterisks.

We can easily see that Scratch can be chosen over C++ if you want to quickly program a multimedia scenario.

C++ program that prints out a triangle shape

//C++
program to print triangle

#include<iostream>

Using
namespace STD;

int
main (){

  Cout<<"\"Triangle
Shape\"\n\n";

  int z=1;

  For (int i=0; i<7; i++) {for (int j=7; j>i;
j--) {   cout<<" "; //
displaying space her   }

    Cout<<"*";   // displaying asterisk here

    if (i!=0){

      for (int k=1; k<=z; k++){

        Cout<<" ";

      }

      Cout<<"*";

      z+=2;

    }

    Cout<<end; // endl is for new line

  }

  For (int i=0; i<=z+1; i++) {

    Cout<<"*";

  }

Cout<<endl;

return
0;

}
