Hi I'm trying to figure this out using infile for this problem to make it less complicated please help and explain each step and which are required to understand this problem. Thank you and I will rate highly, I need the code for this as well

You are given a file consisting of students names in the following form: lastName, firstName middleName. (Note that a student may not have a middle name.) Write a program that converts each name to the following form: firstName middleName lastName. Your program must read each students entire name in a variable and must consist of a function that takes as input a string, consists of a students name, and returns the string consisting of the altered name to print to the terminal. Use the string function find to find the index of ,; the function length to find the length of the string; and the function substr to extract the firstName, middleName, and lastName.
