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

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
