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.

Please help me with this question.
Write a program that declares 3 arrays of size 4 by 3 type integer your program should read the value of the two arrays, add the two array values and store the results in the third array declare another function to add two arrays and store the result in the third one.

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.

By seeing different arguments I become confused which one is right answer. I can't learn anything. It became too much confusing as well as I am losing the reliability.

When you go left to right the rightest part is called trail. Trailing arguments means you should keep default arguments in the rightest position.

Trailing argument means. In function right side argument is trailing argument.
e.g int fun (int, int, int a=4) ; int a=4 is trailing argument.
e.g int fun (int, int, int a=4) ; int a=4 is trailing argument.

One important point to note is that only the trailing arguments can have default value and therefore we must add defaults from right to left.

One more important point is that [D] will be also a correct answer because all arguments of a function will be default arguments.

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