What will be the output of the code snippet given below?
int i;
for(i = 0; i<=10; i++)
{
if(i == 4)
{
Console.Write(i + " "); continue;
}
else if (i != 4)

break;
}
What will be the output of the C#.NET code snippet given below?
byte b1 = 0xF7;
byte b2 = 0xAB;
byte temp;
temp = (byte)(b1 & b2);

temp = (byte)(b1^b2);
Console.WriteLine(temp);
Which of the following statements are correct about the C#.NET program given below?
namespace IndiabixConsoleApplication
{
class SampleProgram
{
static void Main(string[ ] args)
{
int a = 5;
int s = 0, c = 0;
s, c = fun(a);
Console.WriteLine(s +" " + c) ;
}
static int fun(int x)
{
int ss, cc;
ss = x * x; cc = x * x * x;
return ss, cc;
}
}
}

1. An error will be reported in the statement s, c = fun(a); since multiple values returned from a function cannot be collected in this manner.
2. It will output 25 125.
3.It will output 25 0.
4. It will output 0 125.
5. An error will be reported in the statement return ss, cc; since a function cannot return multiple values.

What will be the output of the C#.NET code snippet given below?
namespace IndiabixConsoleApplication
{
class SampleProgram
{
static void Main(string[ ] args)
{
int i = 5;
int j;
fun1(ref i);
fun2(out j);
Console.WriteLine(i + ", " + j);
}
static void funl(ref int x)
{
x = x * x;
}
static void fun2(out int x)
{
x = 6;
x = x * x;
}
}
}

}
}
}
