Variables :

rows : Integer Variable for loop to display rows.

space : Integer Variable for displaying spaces.

i,j,k : Datatype int : Used in for loop.



Logic : 


 for (i = 1; i <= rows; i++)
  {
    for (j = 1; j <= space; j++)
      printf(" ");
 
    space--;
 
    for (k = 1; k <= 2*i-1; k++)
      printf("*");
 
    printf("\n");
  }
 
 
 
 
  // Display Inverted Pyramid 2
 
 
  space = 1;
 
  for (i = 1; i <= rows - 1; i++)
  {
    for (j = 1; j <= space; j++)
      printf(" ");
 
    space++;
 
    for (k = 1 ; k <= 2*(rows-i)-1; k++)
      printf("*");
 
    printf("\n");
  }
