Write a C++ program that exposes C++ ’s rule for operand evaluation order. Write a report (7-15 lines)

The question should be done in C++, please give explanation and running result.  1. Let’s write a function that compares 2 strings and returns true if they were identical, false otherwise. The signature of this function should be: bool word_diff(std::string word1, std::string word2);  For example: std::string str1 = "Hello World";std::string str2 = "hEllO World";std::string str3 = "World";std::string str4 = "Hello World";bool result = word_diff(str1, str2); // Falsebool result = word_diff(str1, str3); // Falsebool result = word_diff(str1, str4); // True   2. Now let’s follow a classical approach to compare the content of 2 files. We should open each file, read their content word by word and compare them until a first mismatch occurs.Let’s implement a function called classical_file_diff that takes 2 arguments each of which is a file name and returns a boolean indicating whether the 2 files are identical or not. The signature of this function should be: bool…

Working on an assignment for C++ codding. Need a little help. I need to write a function that takes in the user's input and returns true if the input contains "polly", "cracker", or "hello". Thanks in advance!

Write code for the C++ function given below: bool isPermutation(string str1, string str2){ //returns true if str1 is a permutation of str2, else returns false
