Problem:
Question- Write a program that takes its input from a file of characters. This file has a single character on each line. So this program is supposed to read each character from the file, storing each char read into a char array. Once the whole file is read, output the array to a new file (can be named as output.txt) modifying all the characters to upper case.
Show the coding of the program that takes its input from a file of characters.
