C program special assignement - HELP ME!

[marcdaven]

---

marcdaven: don't have C programming books to refer to? Naa ra jud na tanan answer sa libro or search sa google.

Basic jud kaayo na nga mga questions, it would require less analysis than making a C program with nested loops.

Kung wala ko masayop, basin mao ni pasabot sa inyo maestra:
Function Parameters:
1. Pass by Value
2. Pass by reference

functions
(depends on what you are going to return)
return (value)

Bro, nag ask man akong maestra about "Unsa pa ang paris sa FORMAL parameters? 2 Types ra na sila..."

Then, wala pa ko ning palit ug book because I'm told nga dili pa daw namo kaayo magamit karon..

Another thing, giusab napud niya ang question: "What happens to this kuno..

main()
{
 .
 ..
 ...
 return 0;
}

[yokyok]

error ni siya sa kasagaran nga compiler, "missing type specifier" pointing to your main()

i think mu error ni cya kai ang "main()" wla mag ask ug return value. i think lng ha.

[marcdaven]

Ahh... OK

Then about sa parameters? Any enlightenment?

[MarkCuering]

it's accepted, compiler will give you a warning message: "warning #2099: Missing type specifier; assuming 'int'." coz once upon a time, C did not have the void type.

Karon pa man ko ka.dungog ug "Formal" parameters oi. Ingna inyong maestra, ang pares sa "Formal" parameter kay "Informal" parameter. Bitaw kidding aside, I haven't heard, nga naay diay "Formal" parameter?

Then, wala pa ko ning palit ug book because I'm told nga dili pa daw namo kaayo magamit karon..

Whoever told you this is a fool. A good C Programming book is an essential tool if you want to learn C Programming. Unless you are born Genius, then you don't need a book.

Might I recommend a few good read?
-Problem Solving and Program Design in C by Jeri R. Hanly and Elliot B. Koffman
-Teach Yourself C (search sa google, naa daghan reference, even free )
-How to Program in C by Deitel & Deitel

Try to secure a copy of the first book I recommend. You might find what you are looking for in that book.

main()
{
 .
 ..
 ...
 return 0;
}

Based on what others have posted, they are correct. You'll get an error, read the explanation of MarkCuering(he is quite a skilled programmer on board).

IMO, mag.error cya kay:
*ang imong main function walay return type, unya at the end of your main function naay statement nga "return 0".
*A general rule in C Programming, every function should return a value, yes include the main() function. If you don't want to return a value, then set the return type to void

Am I correct MarkCuering?

[MarkCuering]

void main() {  ...  }

is not and never has been C++, nor has it even been C. See the ISO C++ standard 3.6.1[2] or the ISO C standard 5.1.2.2.1.

A conforming implementation accepts

int main() { }

and

int main(int argc, char* argv[]) {}

In C++, main() need not contain an explicit return statement. In that case, the value returned is 0, meaning successful execution. For example:

	
#include<iostream>
int main()
{
     std::cout << "This program returns the integer value 0\n";
}

if you want your software to be portable, please make main return int. It does matter.

extern int main(int, char *[]);
int argc;
char *argv[MAXARGS];
int status;

...

status = main(argc, argv);
exit(status);

[benson]

main()
{
 .
 ..
 ...
 return 0;
}

------------------------------------------
I don't know about you guys, but i think their is no error
with this one. In this case, main is by default int isn't it?
Or is it just my compiler showing successfull compilation.

[MarkCuering]

ERRORS are different from WARNINGS.,

the code might give you some warning but not an error, but in some compilers that strictly following standards will disallow you. users can handle the level of warnings/errors in modern compilers.


For C

Under C89, main() is acceptable, although it is advisable to use the C99 standard, under which only these are acceptable:

int main ( void )

int main ( int argc, char *argv[] )

For C++

The following are acceptable uses:

int main ( int argc, char *argv[] )

int main ()

see marcdaven, I stand corrected. I told you can count on MarkCuering
