Program to print alphabet patterns ~ Study Material for BCA Students

Love to generate different patterns with C or C++ compilers:
Check this program, this program is able to generate all alphabet patterns from A-Z.
A pattern for line I Love BcaStuff.
Pattern for all characters is generated separately, but I merged them all in a single collage to better view.

Try this code to generate pattern for all 26 alphabets and heart shape :
//A Program to print all alphabets pattern
#include<stdio.h>
#include<conio.h>
#include<iostream.h>
#include<process.h>
class a_z

 public:
 int i,j,n;
 a_z()

  do
  {
   cout<<"Enter size for pattern (Odd value) : ";
   cin>>n;
  }
  while(!(n>=1&&n<=25));
  if(n%2==0)

   n++;
