Write a program in C++ that takes an input file and reads and stores the sentence in it into a character array. Then it prints all the unique words and the number of times it appeared in a sentence. The output should be saved in a new file. Example of output would be : Suppose sentence in file is : "my name is my name your name is banana" output file would save : my 2 name 2 is 2 your 1 banana 1

P.S it should be done using functions
