Question

I have created one function to return int value for device type as follows ;

public int getDeviceType(string device)
    {
        int temp;
        if (device.ToLower() == "android")
        {
            temp = 1;
        }
        else if (device.ToLower() == "ios")
        {
            temp = 2;
        }
        return temp;

    }

And i wanted to return the type for device.

But it gives me an error that

 "Use of unassigned variable temp"

How can i solve it ?

Thanks.

Just initialize temp with default value like below

public int getDeviceType(string device)
{
    int temp = 0;
    if (device.ToLower() == "android")
    {
        temp = 1;
    }
    else if (device.ToLower() == "ios")
    {
        temp = 2;
    }
    return temp;

}
