1. Function definitions cannot be nested.
2. Functions can be called recursively.
3. If we do not return a value from a function then a value -1 gets returned.
4. To return the control from middle of a function exit function should be used.
5. Function calls can be nested.
namespace CompSciBitsConsoleApplication
{
class SampleProgram
{
static void Main(string[ ] args)
{
object[] o = new object[] {"1", 4.0, "CompSci", 'B'};
fun (o);
}
static void fun (params object[] obj)
{
for (int i = 0; i < obj.Length-1; i++)
Console.Write(obj[i] + " ");
}
}
}
namespace CompSciBitsConsoleApplication
{
class SampleProgram
{
static void Main(string[ ] args)
{
int i;
int res = fun(out i);
Console.WriteLine(res);
}
static int fun (out int i)
{
int s = 1;
i = 7;
for(int j = 1; j <= i; j++)
{
s = s * j;
}

1. If we do not return a value from a subroutine then a value -1 gets returned.
2. Subroutine definitions cannot be nested.
3. Subroutine can be called recursively.
4. To return the control from middle of a subroutine exit subroutine should be used.
5. Subroutine calls can be nested.
namespace CompSciBitsConsoleApplication
{
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;
}
}
}
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.
It will output 25 125.
It will output 25 0.
It will output 0 125.
An error will be reported in the statement return ss, cc; since a function cannot return multiple values.Suggested Topics
