1) We have a legacy C library that is indispensable in a project. The code content of this library is not to be modified, but the library offers the ability to register callbacks that are preferably coded in C++ by the developer utilizing the library. How can such a callback mechanism be possible to construct, and what is an important detail concerning the C library and the signatures of the registered callback functions? Explain. 2) Similar to the C library in the previous question, a C++ library allows callback functions to be registered for utilization as well. Would you expect the C++ library to make use of the same callback mechanism as suggested in the previous question, or are there better alternatives that the C++ library possibly can offer? Explain.

What should be a function declaration If i am making a programm to divide 2 numbers using function

Please explain

float div(int,int); Is it correct??

For floating division should i write float div(float a,float b);

#include<stdio.h> float div(float ,float ); int main() { float num1,num2,answer; printf("enter 1st number:"); scanf("%f",&num1); printf("enter 2nd number:"); scanf("%f",&num2); answer=div(float,float); printf("\n value= %f",answer); return 0; } float div(float x,float y) { float result; result=x/y; return result; }

Trying to make but getting error

Ok let me try

For the 2nd question, I personally would expect by default that a C++ library will have some support for functors (not necessary std::function, but preferably) and lambdas. So if I capture some variables in a lambda and pass it as a callback I'll be sure that the captured objects will be destroyed correctly.

Or you mean that you have no choice but to use it?

bruh

please is there any APP for windows which i can use for java

Hello, can header files use recursive functions?

Can someone provide me link from where I can get whole knowledge of git and github about clone , fork and all other things

I created a header file that contains a recursion but when function from header is called, I get the error message, multiple definition of function

Anyone knows?

I created a header file that contains a recursion but when function from header is called, I get the error message, multiple definition of function

That's not related to recursion, why don't you move it to cpp and leave only the declaration in the header?

Ok

You can read about One Definition Rule (ODR) for the details about the error itself.

Guys, who can help me? Because of the low quality of the online study, we are 400 student are having final test in c++ and No one of them can answer even a good answers Please guys I need some one who can help us Just to solve some questions of codding in C++ If you help me that means that you helped more than 400 student, they will be thank full for you

What does this mean

Int arr[100] ={0}

An array of 100 integer elements called arr with the first element initialized with the value 0

who is good in c programming

It's not an error?

hahahahhaha

need a good man in c

?

good in c programmin

It's not an error?

can a recursive function be void

yes, a function with return type void can be called recursively

But how a recursive function be void

Can i use function type void 🤨🤨🤨

If you want to print the fibonacci series you're better off not using recursion in the first place. But yes, you could use a void returning function to print the fibonacci series.

Media doesn't allow how i show ss of code
