Thanks for the help, but i tryed both solutions posted and
still not working. :/
I get erros to compile the code posted by simendsjo. I try
modify at my own, but without success. The code suggest by
Timon Gehr compiles, but not work.
Honestly speaking, i didn't have enough knowledge to
understand the solutions offered (yet). What is the smallest
way to use the "read_bool"?
Besides, one version of that tutorial in portuguese would be
great =D
This works:
import std.stdio, std.string, std.conv;
bool read_bool(in string message) {
while(true) {
write(message, " (false or true): ");
string input;
do {
input = readln().chomp();
} while(!input.length);
writeln("INPUT: '", input, "'");
try
return input.to!bool();
catch {}
}
}
void main() {
write("How many are we? ");
int personCount;
readf(" %s", &personCount);
write("How many bicycles are there? ");
int bicycleCount;
readf(" %s", &bicycleCount);
write("What is the distance to the beach? ");
int distance;
readf(" %s", &distance);
bool existsCar = read_bool("Is there a car? ");
bool existsLicense =
read_bool("Is there a driver license? ");
}
$ rdmd read_bool
How many are we? 10
How many bicycles are there? 1
What is the distance to the beach? 2
Is there a car? (false or true): true
Is there a driver license? (false or true): false
Very interesting way to solve the problem (at least for a noobie
like me ^^ ). Thanks for the help!
