Re: Best way to check for an element in an array?

[FrankLike via Digitalmars-d-learn]

Hi,everyone,
 It works maybe the best:

import std.stdio;

template isin(T){
    bool isin(T[] Array,T Element){
        foreach(T ArrayElement; Array){
            if(Element==ArrayElement){ return true;}
        }
    return false;
    }
}

void main(string[] args)
{
    int[] stuff=[0,1,2,3,4,5,6,7,8,9,10];

    if (stuff.isin(2))
    {
        writeln("Hello World!");
    }

        string[] strs =["Hello","world","hi","Everyone"];
        if(strs.isin("Hi"))
        {
                writeln("find Hi");
        }
        else
        {
                writeln("not find Hi from: "~strs);
        }
}
