These are the required co‎des for the question.

1. In Java.

public class Pattern    {

   public static void main(String args[])  {  

       for(int i=1;i<=4;i++)   {

           for(int j=1;j<=i;j++)

               System.out.print("@ ");

           System.out.println();

       }

   }

}

2. In Python.

for i in range(4):

   for j in range(i+1):

       print("@ ",end=" ")

   print()

OR

print("\n".join(str("@ ")*i for i in range(1,5)))

3. In C

#include <stdio.h>

int main()  {

   for(int i=1;i<=4;i++)   {

       for(int j=1;j<=i;j++)

           printf("@ ");

       printf("\n");

   }

   return 0;

}

4. In C++

#include <iostream>

using namespace std;

int main()  {

   for(int i=1;i<=4;i++)   {

       for(int j=1;j<=i;j++)

           cout<<"@ ";

       cout<<endl;

   }
