Step 1 -> function int printpattern(int n)
   If n>0
      Printpattern(n-1)
      Print *
   End IF
End
Step 2 -> function int pattern(int n)
   If n>0
      pattern(n-1)
   End IF
   Printpattern(n)
   Print </p><p>
End

#include <stdio.h>
int printpattern(int n) {
   if(n>0) {
      printpattern(n-1);
      printf("*");
   }
}
int pattern(int n) {
   if(n>0) {
      pattern(n-1); //will recursively print the pattern
   }
   printpattern(n); //will reduce the n recursively.
   printf("</p><p>"); //for new line
}
int main(int argc, char const *argv[]) {
