considering the following code is already written as a part of the program. 4
struct Member
{
int MNO;
char MNAME[20];
Member *Next;
};
Class QUEUE
{
Member *Rear,*Front;

public:
QUEUE(){Rear=NULL;Front=NULL;}
void ADDMEM();
void REMOVEMEM();
~QUEUE();
};

4. (a) Aditi has used a text editing software to type some text. After saving the article as
WORDS.TXT, she realised that she has wrongly typed alphabet J in place of
alphabet I everywhere in the article. 3

Write a function definition for JTOI()in C++ that would display the corrected
version of entire content of the file WORDS.TXT with all the alphabets “J” to be
displayed as an alphabet “I” on screen.
Note : Assuming that WORD.TXT does not contain any J alphabet otherwise.
Example :
If Aditi has stored the following content in the file WORDS.TXT :

WELL, THJS JS A WORD BY JTSELF. YOU COULD STRETCH
THJS TO BE A SENTENCE

The function JTOI( ) should display the following content :

WELL, THIS IS A WORD BY ITSELF. YOU COULD STRETCH
THIS TO BE A SENTENCE
