What will be the output of the following program?
#include<iostream.h>
long BixFunction(int x, int y = 5, float z = 5)
{
return(++x * ++y + (int)++z);
}
int main()
{
cout<< BixFunction(20, 10);
return 0;

Solution:
x = 20.
y = 10.
z = 5.
++x = 21.
++y = 11.
++z = 6.
21*11+6 = 237.
x = 20.
y = 10.
z = 5.
++x = 21.
++y = 11.
++z = 6.
21*11+6 = 237.

x and y always refer the current value passed into 2nd fun so x will become 20 and y become 10. Whenever the pointer goes into the return that time x will become 21 and y will be 11 and z will be 6.21*11+6=237 that is final answer.

See in float z = 5.0 then in int z = 5 we can take like this. I am right?

What does the Bixfunction (20, 10) mean ?
If it indicates x=20, y=10, but y=5 was given in declaration ?
If it indicates x=20, y=10, but y=5 was given in declaration ?

I think there will be an error as there are only two parameters passed where as in function definition we can clearly see there are 3 variables.

Please any one explain me, how this method takes two arguments?

Here from the main function,
x=20,
y=10,
z=5 (as it is from the function definition)
So the computation for
(++x * ++y) + ++z
goes like
++x = 21
++y = 11
21*11 = 231
++z = 6
231 + 6 = 237.
x=20,
y=10,
z=5 (as it is from the function definition)
So the computation for
(++x * ++y) + ++z
goes like
++x = 21
++y = 11
21*11 = 231
++z = 6
231 + 6 = 237.

Default arguments pass the values from right to left order in called function.

Actually here in the main function the function called bixfunction is being called upon by invoking 2 arguments which won't happen because the bixfunction has 3 arguments to set it to operate for the values being sent to bixfunction. So the program will terminate due to calling a function which is not available.

There is "No ERROR" and 237 is the correct answer described by '@Bala'.
