can i send the picture of code
HaiNahi
write a program in c language ,if a student scores 40% total and atleast 30% marks in each subject then he is pass or he fails ,no of subjects is 3 phy,chem,math
You want a program to generate random values of marks?
Anonymous
then what can i do now
Anonymous
@swastik yes user will puy the marks
Anonymous
how to do in pastebin
HaiNahi
So we have to test if marks entered meet the conditions or not?
Anonymous
@swastik ,yes user will put say 80 % marks then he is pass
HaiNahi
I think don't divide by three u can add the thing upto 300 and check the mark wrt 240 else floats will come
Anonymous
i dont get it
HaiNahi
Take the three marks add it if bigger than 240 pass or else fail
Anonymous
no user will first put his marks in math ,then phy,then chem
HaiNahi
Yeah you can add the three inputs

What's the difference between int main () and void main()?
Roshan
What's the difference between int main () and void main()?
Int returns int data type void doesn't. Also don't use void main() as it is not compiled by some compilers...

Also there is no need to write return 0 in int main() as it's a special function. Return 0 is done by itself

Thanks

in the industry you using void main alot

Most of my tasks require void main

You dont need to. As int main() is same as void main() in VS

void is when you don't need returns, like if you making a matrix call function you can use void, and void main usually just the main with all the functions, I don't know why, but my friends that works already in the industry usually uses void main on their codes

One is correct the other one is not. https://isocpp.org/wiki/faq/newbie#main-returns-int

I doubt that since gcc yields errors for void main. I have not seen the void version being used in production code

There is only one place where void main is correct, but you guys won’t be interested

Maybe only on my country... Im not sure.. Anyway I'm learning C just for the basic.. I want to move to c# afterward

void main is not valid C or C++

Minor Spoiler: Where void main() is correct

Read the chat title please
You said it don't valid on c c++, I said maybe it's on c#, I don't know, I don't think my friends will lie to me.. And on the university that ask you to do void main most of the time...

In C# main needs to be static, so it's signature differs as well

Well it's not ISO C anyways as you said :)

Returning void from main
As a Microsoft extension, the main and wmain functions can be declared as returning void (no return value). This extension is also available in some other compilers, but its use isn't recommended.
Even MS recommends not to use void main

I see.. I'll ask again my friends why.. Thank you

Yeah and also question about void main was mentioned on the one of f.a.q. on Stroustrup website
Roshan
I didn't answer. Your quotes were at wrong place.
scanf("%d",&number);
This is the correct order.

More like ANSI C :P
Microsoft has C++ going native conference since 2012 and employes such members of C++ Standards Committee as Herb Sutter and is constant sponsor of Cppcon I'd say they do love C++.
They had most of C99 support only recently. So they don't really love C at all.

I looked up about "literal classes" which will make passing non-type non-primitives as templates parameters possible
Apparently for a class to be a literal one of its condition is "All base claases and non-static data members are public and not mutable"
Any Idea of why the data members must be public?

how can I use the arguments of (mebInfo) function in (mebCost) function?!

Literal type should be aggregate type. And aggregate type is the one that support segregate initialisation. Meaning that you should be able to access all its member

Use appropriate parameters to pass information in and out of a function. (Do not use any global variables.)

Yeah, but why does the compiler need it to be so for making it a non-type parameters in template?

A type is a literal type if it is:
- cv void; or
- a scalar type; or
- a reference type; or
- an array of literal type; or
- a possibly cv-qualified class type that has all of the following properties:
- it has a constexpr destructor ([dcl.constexpr]),
- it is either a closure type ([expr.prim.lambda.closure]), an aggregate type ([dcl.init.aggr]), or has at least one constexpr constructor or constructor template (possibly inherited from a base class) that is not a copy or move constructor,
- if it is a union, at least one of its non-static data members is of non-volatile literal type, and
- if it is not a union, all of its non-static data members and base classes are of non-volatile literal types.
