    this should process all the names?
    Code:
    void load_ages ( void ) {
         int i ;
         char choice[BUFSIZ]; 
        
         printf( "\n%sEnter the ages of the family you entered!.\n" , name );
         printf( " ( q to stop ) :\n ");
         do {
         printf ( "family member :  %s \n", tree[i].name );
         } while ( choice[0]!= 'q' );
         
    }
    it still crashes

    ok this works but im stuck with the for loop im not happy with! also its picking up the q how do i fix that?
    Code:
    void load_ages ( void ) {
         int i  ;
         char choice[BUFSIZ]; 
        
         printf( "\n%sNow we will enter the ages of the family you entered!.\n" , name );
         printf( "hit enter after each age ( q to continue ) :\n ");
         for ( i = 0; i < MAX; ++i) {
         printf ( "family member :  %s \n", tree[i].name );
         puts("enter the age now!");
         fgets ( choice, sizeof ( choice ) , stdin );
         sscanf( choice , "%i" , &tree[i].age);
         if ( choice[0] == 'q' )
         display_menu();
           }
    }
    output:
    Code:
    what is your name : luke
    *********************************************
                       ** welcome to the family catolog **
    
    
    Family tree menu:
     1. Enter names
     2. Enter ages
     3. display family tree
     4. Search family member
     5. quit the program
    1
    luke
    enter the all the names of your family.
    hit enter after each name ( q to stop ) :
    padme
    leia
    q
    
    luke
    Now we will enter the ages of the family you entered!.
    hit enter after each age ( q to continue ) :
     family member :  padme
    enter the age now!
    23
    family member :  leia
    enter the age now!
    12
    family member :  q
    enter the age now!
    1
    family member :
    enter the age now!

    Why are you so stupid? If you want it to stop as soon as you enter q, then don't ask it for age before you check for q! Come on man, think! This thread shouldn't be four pages long, and wouldn't be, if you actually thought about what you're trying to do, versus what you're really doing.

    Hope is the first step on the road to disappointment.

    Code:
    void load_family ( void ) {
         int i ; 
         char choice[BUFSIZ];
    
         printf( "%senter the all the names of your family.\n" , name );
         printf( "hit enter after each name ( q to stop ) : \n");
         i = 0;
    while( fgets( choice, sizeof choice , stdin) != NULL ) { 
       sscanf ( choice , "%s" ,  tree[i].name );
       if ( choice[0] == 'q' || i == MAX) 
          load_ages(); // go to the load_ages function
       ++i;
         }
         
    
         
    }
    this thing
    Code:
    while( fgets( choice, sizeof choice , stdin) != NULL ) { 
       sscanf ( choice , "%s" ,  tree[i].name );
       if ( choice[0] == 'q' || i == MAX) 
          load_ages(); // go to the load_ages function
       ++i;
         }
    an obvious good question : do i want to store the name first, or check the validity of the input first?

    don't take that as a form of offence even if he intended to do so... if i were you, i'd take that as a good point

    the thing is not whether you are smart enough, it's your tries that count...

    I have learned C for about a year now and I sometime still make some silly mistakes... so don't worry too much about making mistakes, worry about learning from them

         printf( "%senter the all the names of your family.\n" , name );
         printf( "hit enter after each name ( q to stop ) : \n");
         i = 0;
         while( fgets( choice, sizeof choice , stdin) != NULL ) { 
         sscanf ( choice , "%s" ,  tree[i].name ); 
         ++i;
         if ( choice[0] == 'q' || i == MAX)

    no you still don't get what i meant...

    see, after you fgets (reading the user's input), u copy whatever the input to the designated place using sscanf...

    maybe it's good if you actually test the validity of the input (ie, whether the user type in 'q'), and if so, you don't want to sscanf it rite?

    Code:
    while( fgets( choice, sizeof choice , stdin) != NULL ) { 
       sscanf ( choice , "%s" ,  tree[i].name ); // put everything in the struct or
       if ( choice[0] == 'q' || i == MAX)        // checking the validity of input first?
            display_menu();
       ++i;

    Code:
    void load_family ( void ) {
         int i ; 
         char choice[BUFSIZ];
    
         printf( "%senter the all the names of your family.\n" , name );
         printf( "hit enter after each name ( q to stop ) : \n");
         i = 0;
         while( fgets( choice, sizeof choice , stdin) != NULL ) { 
         if ( choice[0] == 'q' || i == MAX)
         {
         printf("we will now enter there ages\n");
         load_ages();
         }
         sscanf ( choice , "%s" ,  tree[i].name ); 
         ++i;
    
         }
