C++The file text.txt contains a sentence text written in all small letters and does not have any punctuation marks, no numbers, no symbols except for spaces.You are required to write a program which accepts an operation code, and zero to two inputs depending on the operation code. Based on the operation code, you will call three versions of the overlaoded function textProcessing as follows:Operation 0: The function removes all vowels from the ORIGINAL sentence. The vowels considered are the small letters (a, e, i, o, u y, and w).Operation 1: The code further asks for one lowercase letter to be input by the user. If the character is not a lower case letter, the code outputs Invalid. The function returns the distance (difference) between the letter first occurence and last occurence in the text. If the letter does not occur in the sentence, it returns 0.Operation 2: The code asks for two lowercase letters to be input by the user. If the characters are not lower case letters, the code outputs Invalid. The function replaces the original letter by the new letter in the ORIGINAL string.Any other opcode: the code outputs Invalid. 7:44Input:2aAOutput:the earth is A very small stAge in A vAstcosmic ArenA1 #include 2 #include 3 #include 45using namespace std;67 void textProcessing (string&inputstring);8int textProcessing (conststring &inputString, charletter);9void textProcessing (string&inputString, char orgChar,char newChar);1011 int main() {12unsigned short operation;13cin >> operation;1415string sentence;16fstream inputstream;17inputstream.open("text.txt");1819while (!inputstream.eof()){2021getline (inputstream,sentence);22if (sentence.
