* * * * *

hey there!

Well this is the basic code for making this triangle :

int main()
 {
    cout<<"\"Hollow Triangle Shape\"\n\n";
   int z=1;
 
   for (int i=0; i<7; i++)
   {
     for (int j=7; j>i; j--)
     {
       cout<<" "; // displaying space here
     }
     cout<<"*";   // displaying asterisk here
 
     if (i!=0)
     {
       for (int k=1; k<=z; k++)
       {
         cout<<" ";
       }
       cout<<"*";
       z+=2;
     }
     cout<// endl is for new line
   }
 
   for (int i=0; i<=z+1; i++)
   {
     cout<<"*";
   }
 
 return 0;
 }

I can't help you much as i dont have my PC right not ,but this is the basic step to make that out.

IN C++:

int main() {

//Declaring the variables.

int rows, position;

//Prompts user to enter number of rows.

printf("Enter the number of rows in the triangle: ");

scanf("%d", &rows);

//Prints the first row of the triangle.

for (position = 1; position <= rows-1; position++)

printf(" ");

printf("*\n");

//Prints the middle part of the triangle.

//Prints the last row of the triangle.

for (position = 1; position <= rows*2-1; position++)

printf("*");

return 0;
