Default arguments

[Sathyaish]

How do you define an argument for a function such that the argument is
optional and has a default value assigned to it? I am sorry but I am
having memory lapses.

You use some other language with that capability, such as Ada.

int funcDefArgs(int a, int b = 4);

Remember to provide the default arguments only at the time of the decl.
of the function and **not** at definition.

Also, the rightmost arguments can be default. Soo, while 1. is wrong, 2
is prefectly fine.

1. int funcDefArgs(int a, int b = 4, int c);
2. int funcDefArgs(int a, int b = 3, int c = 2);

Try going to a pharmacist and ask for memory plus capsules. It might
help

And of course, this is a solution only for _Not_C_Language_.
It might be C++ but I cannot remember when in comp.lang.c;
comp.lang.c++ might know.

Sorry but I did not get that.

Sorry but I did not get that.

Sorry, my fault:
The short of it is that this is not possible in C, only in C++,
so your answer is wrong.

Ah!! Yup apologies for posting a wrong solution.

2. int funcDefArgs(int a, int b = 3, int c = 2);

You need quotes around each of the arguments, like "int b = 4", and
don't forget that the prototype has to be something like
int funcDelArgs( char *s1, char *s2, char * s3);
