What is mean by trailing argument?

Only the argument at the end of the argument list can have default arguments.
Because if you insert the default arguments at the middle of the argument list, the compiler would lose track of what arguments went where.
void badfunc(int, int=2,int) // Wrong way...
void okfunc(int, int=2, int=5); // Correct.

@Anurag.
You can have more than one default arguments, all these should be at the end of the argument list.

If a function has three arguments then it is not necessary that the trailing argument will be default argument.

@Priya & @Jayati Trailing argument means the last argument in the parameter list of function prototype.

If you have not defined default argument in function definition then there will be no default argument. By the way default argument always come in RHS of argument list.

The default argument can be only given from right to the left in the given parameter list!
