Please help if you can i am stuck!

[blaze5488]

What is suppose to happen is that I am suppose to take a string like "Micheal Jordan" and reverse it and return it with a comma after the last name. like "Jordan, Micheal" but that is not what i am getting can you help please. I have also included the directions for this part as well.

The public String GetInfoLastNameFirst() method should create a first name string and a last name string from this.name. You must use a loop to create the first name string. You must use a loop to create the last name string. (HINT: we created new strings from old strings in lecture, exercises, and studio of September 22/23.) Then, similarly to the method GetAllInfo(), this method should return all the info about the candidate, but do so with the last name first, followed by a comma, followed by the first name, then tab, then party, then tab, then votes, then new line. You must use a loop, to create the first name and last name strings. (Clever coding can do it with one loop; straightforward coding uses two.)

/// <summary>
        /// reverses the first and last name and puts a comma in between
        /// </summary>
        /// <returns></returns>
        public String GetInfoLastNameFirst()
        {
            string FN = name;
            string LN = name;
            int i = 0;
            int j = 0;
            int location = name.IndexOf(" ");
            while (i < location)
            {
                
                FN = i.ToString() ;
                i++;
                
            }
            while (j > location)
            {
                LN = j.ToString();
                j++;
            }

            return LN + ',' + ' ' + FN + "\t" + this.party + "\t" + this.votes + "\r\n";
            
        }

One, where does name come from? Is it a global variable or were you supposed to pass it the function? Two, what are the ToString and IndexOf functions? This line doesn't make sense.

FN = i.ToString() ;

You defined i as an int. int is not a class, so you can't use the dot. It looks like you are trying to use Java functions in C++. There is no String class in C++, unless you wrote it yourself.

public String GetInfoLastNameFirst()

There IS a String class in Java. Is this a Java question or a C++ question?

Well if it's C++, get rid of ToString and IndexOf and make String lower case if you didn't write these functions and didn't write a String class.

http://www.cplusplus.com/reference/string/string/
http://www.cplusplus.com/reference/clibrary/cctype/

These libraries might contain some functions that are useful to you. I don't understand what you are trying to do in that function, but to make it understandable at all, get rid of all the Java-like function calls.

What i am trying to do is take a full name like "Adam Sandler" and break it up so that i can return it as "Sandler, Adam" but I don't know how to break it up so i was trying to count the letters until i got to the space in between "Adam Sandler" and then return that as FN (aka first name) and then make all char's after the space be LN (aka last name).

That's a reasonable solution. It looks like you're using a non-standard string class, but this might help you figure out how to fix your code. It's based on your solution:

#include <iostream>
#include <string>

int main()
{
  std::string src = "Adam Sandler";
  std::string first;
  std::string last;
  std::string::size_type i = 0;

  while ( i < src.size() && src[i] != ' ' )
    first += src[i++];

  // Skip the whitespace
  while ( i < src.size() && src[i] == ' ' )
    ++i;

  while ( i < src.size() )
    last += src[i++];

  std::cout<< last <<", "<< first <<'\n';
}
