    How to use the string() function?

    I am working on an assignment that will return the string length in the number of characters. Here is what I've done so far, but I have no clue how to use the string() function. Any help would be appreciated.

    Code:
    #include <iostream>
    #include <string>
    
    using namespace std;
    
    int main()
    {
    	cout << "Groom's Name (last,first): ";
        string groomfirst;
        string groomlast;
        cin >> groomlast >> groomfirst;
        
        
        cout << "Bride's Name (last, first): ";
        string bridefirst;
        string bridelast;
        cin >> bridelast >> bridefirst;
    
    	size_t groom;
    	groom = groomlast.length();
    	size_t bride;
    	bride = bridelast.length();
    
    	cout << "Length of Groom's LAST name: " << groom  << endl;
    	cout << "Length of Bride's LAST name: " << bride << endl;
        
        return 0;
    }

    don't understand your question but
    Code:
    	string groom = groomlast.length();
    	string bride = bridelast.length();
    has to be
    Code:
           unsigned long groom = groomlast.length();
          unsigned long bride = bridelast.length();

    try looking up the return type of the length function......I think you'll be able to figure out what you are doing wrong from there.

    Thanks. I got it to work!

    But I must move on to the next level where I have to store
    lastname,firstname into one variable and use the substr function to extract the last name and display the length of the last name. I do know it should be something like:

    name.substr(0,?)

    Does anybody know how to locate the comma, or is there an easier way?
