function overloading == polymorphism?
If so, read on...
Code:
void meh(int myvar);
void meh(char myvar);
void meh(int myvar1, char myvar2);
This is the declaration of two functions, but note that they have
the same name. So, when you call the function[s] the function[s] is
executed that has the appropriate argument(s)
Note: I have not checked the above code and I'm a lousy C++ coder...
No, I know what function overloading is.
Just what's the use of it?
Quote:actoully, C do have function overloading, the C99 standard alowes it.
Can you post a link to back that up? I can't find any thing on C99 allowing function overloading, heres a list of the features that are in C99:

Its quite useful in OO languages, where a method in a class could intuitively be called with different arguments. For example:
Code:
public class Player {
private String lastName, firstName;
/* SetName for players with only a first name */
void setName(String name) {
firstName = name;
}
/* SetName for players with a first and last name */
void setName(String fName, String lName) {
firstName = fName;
lastName = lName;
}
/* Return the players name */
String getName() {
return firstName + " " + lastName;
}
}
Oh, come on, talk about laaazy.
Code:
void whatever(int um,int blarg)
{
if (blarg==NULL)
/* blarg argument not supplied */
else
/* both args supplied /*
}
It's not technically "not supplied" but seriously, set a value to signify that the player doesn't have a last name.
Can't we all agree that QBasic is way better then C/C++ or Java?
QB is an easy language.
Take a look at what it stands for. It's all true, minus the "Quick" part.

Nope. You cant really compare them anymore now, Qbasic was fun, but its different, and too old to compete against the latest compilers. Besides personally, i like C.
Anyways one point: If c++ is c with classes, then java is classes without c. Really, theres more to c++ then just classes.(namespaces,templates) and althouth you could argue the forced casting is a pain, it does help hide some hard to find bugs.
Isn't C older then BASIC?
Yes, I believe so...Bell Labs made B in the 70s, and then they wanted a new language...guess what it was called? :lol:
Not the language, the compilers. C compilers are constantly updated and released, qbasic is and will remain the same. You never stated basic, you said "qbasic", which is itslelf a Basic compiler. and basic was in the 60's so no.(although it looked very different at the time)
Also c is constantly modified, the latest version C99 is practicly brand new.
