4. (a) Polina Raj has used a text editing software to type some text in an
article. After saving the article as MYNOTES.TXT, she realised that
she has wrongly typed alphabet K in place of alphabet C everywhere
in the article.
Write a function definition for PURETEXT() in C++ that would
display the corrected version of the entire article of the file
MYNOTES.TXT with all the alphabets ――K‖‖ to be displayed as an
alphabet ――C‖‖ on screen. 3
Note : Assuming that MYNOTES.TXT does not contain any C alphabet
otherwise.
Example :
If Polina has stored the following content in the file MYNOTES.TXT :

I OWN A KUTE LITTLE KAR.
I KARE FOR IT AS MY KHILD.

The function PURETEXT() should display the following content :

I OWN A CUTE LITTLE CAR.
I CARE FOR IT AS MY CHILD.

(b) Write a definition for function COUNTPICS( ) in C++ to read each
object of a binary file PHOTOS.DAT, find and display the total
number of PHOTOS of type PORTRAIT. Assume that the file
PHOTOS.DAT is created with the help of objects of class PHOTOS,
which is defined below : 2

class PHOTOS
{
int PCODE;
char PTYPE[20];//Photo Type as “PORTRAIT”,“NATURE”
public:
void ENTER()
{
cin>>PCODE;gets(PTYPE);
}

void SHOWCASE()
{
cout<<PCODE<<":" <<PTYPE<<endl;
}
char *GETPTYPE(){return PTYPE;}
};
