[kerze via Digitalmars-d-learn]

hmm the paste is away ?!? here i post my source one more time.

[code]
import std.stdio;
import std.string;

struct Human {
     string name;
     ushort age;
};


void print_human_list(Human[] human_list){
     foreach(human; human_list){
         writeln(human.name);
	writeln(human.age);
     }
     writeln("");
}



void add_new_human(Human[] human_list){
     ushort age;                               //
     write("Name: ");                          //  The Output is
     string name = strip(stdin.readln());      //  Name: Age:
     write("Age: ");                           //  And the Error
     readf(" %u", &age);                       //  
std.conv.ConvException@/usr/include/dlang/ldc/std/conv.d(1968):
     Human tmp_human = {name, age};            //  Unexpected 's' 
when converting from type LockingTextReader to type uint
     human_list ~= tmp_human;
}



int main(){
     Human[] human_list;
     char choice;

     for(;;){
         writeln("A)dd New Human.");
         writeln("P)rint Human List.");
	writeln("Q)uit.");
	write(": ");
         readf("%c", &choice);
	switch(choice){
             case('A') : add_new_human(human_list);
	    case('P') : print_human_list(human_list);
	    case('Q') : return 0;
	    default   : continue;
	}
     }
}
