Has anyone worked with Assimp?
I've downloaded the library source
Should I be using that entire thing or just the code folder?
I am trying to use it with add_subdirectory() in CMake in my project
I am using MinGW to compile
I am using C++ 17

hello
Ekal
ive got a question
Ekal
im on a mini project
Ekal
it is said to make a program
Ekal
Example project:
The mini project can calculate:
1. Area of square
2. Area of triangle
3. Volume of cone
4. Average of 5 numbers
5. Body Mass Index (BMI)
Ekal
my question is how to merge or combine two calculation??
Garima
my question is how to merge or combine two calculation??
You can use switch statements, this will give user a choice that which calculation they want
Ekal
thankyou i will try that

I have some weird problem
I declare CLEAR this way
#ifdef _WIN32
const char CLEAR[3] = {'c', 'l', 's'};
#else
const char CLEAR[5] = {'c', 'l', 'e', 'a', 'r'};
#endif
but when i pass it to a function doing system(CLEAR) it is interpreted as "clsE0'a" on windows (on linux "clear" works) can anyone point me what might be the case?
Pavel

You need to add a zero at the end of your buffer, otherwise your function will read out of bounds of it

what the difference between gcc and g++

You need to add a zero at the end of your buffer, otherwise your function will read out of bounds of it
1) '0' or '\0'?
2) do i need to increase sizes of the arrays to 4 and 6 after adding it?
Pavel

2) do i need to increase sizes of the arrays to 4 and 6 after adding it?
1) '\0'
2) yes, it should be one item longer to fit the zero

tho on linux it was working all the time, are unixlike os-es more smart when it comes to c-strings?

In general, reading out of bounds is UB, so sometimes it can result in working as intended.
What happened probably, is on Linux there was zero byte in the memory right after your buffer (likely from some other variable/constant)

Hello everyone
Is there a "type casting" for functions in C++ ?
I mean if i have an "int function(int , char )" and in a special case i want to make this function return string, can i make that?
Or is there another way to do this?
Sorry for my long message but this group helps me a lot

Are conditions for this special case being checked at runtime?

Maybe you can split this function into two separate ones and simply overload it.

I guess yes
It is a function which is calculator.. and division by zero is not possible, so i want to cout a message that says "cannot be calculated".. but it could be a zero like 1 - 1
@skelly37
Official hooligan of Pius XII
well, you can also always return a string and then use stoi() if possible, if you want it to be really straightforward, like that
string test()
{return "1";}
int main()
{int test1 = stoi(test());}

Well, you can return std::variant<int, std::string> as a possible way, but that will be rather ugly I think.
You can return the value using by-reference argument and return an error code (bool or int) from the function to indicate an error. Also ugly.
Or return std::pair<int, bool> or std::pair<int, std::string> (first one is how it's usually done in STL) (ugly? I guess so)
You can throw an exception with the error and catch it outside, that also will be ugly, but probably a bit better, probably.

i'd return a pointer to an array looking like { bool if it could be calculated, int result or 0}
if(array[0))
cout array[1]

stoi() literally converts string to integer

@skelly37

In this case I agree with skelly37, you can just return string, assuming the result will be converted to string in the end anyway.
Otherwise I would use std::variant here

Get a good book and start programming! Codesignal has a variety of challenges for every difficulty level. Once you're stuck, we're here to help.
Btw Linux is written in C, not C++. Linus Torvalds has pretty strong opinions about this.
class Person(Skills): name = str("Ankush Bhagat")
How I do that :
If (os == Android)

you can also use #else in here

Here are another cases. Compiler macros are very useful sometimes

That would be different shell. Each call to system() spawns:
/bin/sh -c cmd
So you lost the var in the second call.
class Person(Skills): name = str("Ankush Bhagat")
