    Code:
    int length, longest = 0, longest_idx= 0; //idx = index
    
    //inside your for for loop, add:
    
    length = strlen(name[i]);
    
    if(length > longest) {
        longest = length;
        longest_idx = i;
    }
    
    printf("\n the longest name is: %s, which has %d letters", name[longest_idx], longest);
    Try putting that kind of logic, into your program.

    Adam... Do you really not know how to do this?

    Look at the code you've got... arrays, indexes, loops, input, output...
    If you actually wrote that code you should easily be able to work out the rest.

    Egad! While not related to your longest string issue, the following should be addressed:

    Adak's got you on the right path though.
