You made a simple logic error. Change the following || to &&:
}while(choice != 'q' || choice != 'Q');

I think it should not give this error
good but until now I do not understand why after I enter with
data in the function add_human
the same is not printed when I choose the 'p' or 'P' option
in the case
void print_list(Human[] human_list)
{
foreach(human; human_list)
{
writefln("\nNome: %s",human.name);
writefln("Peso: %0.2f",human.peso);
writefln("Idade: %d\n",human.age);
}
}
It's because add_human is appending to its own array. Change
it to by-ref:
void add_human(ref Human[] human_list)
Ali
while(choice != 'q' || choice != 'Q');
doesn't seem to exit the loop, while this works:
while(choice != 'q');
or
while(!(choice == 'q' || choice == 'Q'));
wouldn't it be better to use a labeled statement instead?
endless : while(true)
{
...
switch(choice)
{
...
case 'Q':
case 'q': break endless;
...
}
}
It's good that it worked out here.
