How to Demonstrate Working of Pointers

/* Source code to demonstrate, handling of pointers in C program */

#include <stdio.h>
int main(){
   int* pc;
   int c;
   c=22;
   printf("Address of c:%u\n",&c);
   printf("Value of c:%d\n\n",c);
   pc=&c;
   printf("Address of pointer pc:%u\n",pc);
   printf("Content of pointer pc:%d\n\n",*pc);
   c=11;
   printf("Address of pointer pc:%u\n",pc);
   printf("Content of pointer pc:%d\n\n",*pc);
   *pc=2;
   printf("Address of c:%u\n",&c);
   printf("Value of c:%d\n\n",c);
   return 0;
}

C Program Print Number Pyramid Pattern
In Each Iteration we are moving downward so increment "y". For each new 'Iteration' we are starting from beginning but one 'co-ordinate' back so decrement x. 'Moves Cursor Position'
