How does pipelining improve performance?
What are the limits on how much a processor performance can be improved upon using pipelining?

In simple words it divides the task for processors..

It doesn't improve it better than threads. However, the reason it's popular is that it allows for very modularized programs (gnu-mentality).
BinaryByter
excellent question, btw
Oluwaseyi
Thanks
BinaryByter
the limit for performance is how fast you manage to get your different softwares to work together. if you wait for ages for a message from program 1, it doesn't really improve the efficiency a lot
BinaryByter
(and obviously the CPU clock speed)

I have just read the message and understand. Currently learning C, but just joined to follow the discussion. Thank you for the welcome.

Guys how do i pass a const char *v[15] to a function by reference??
Riccardo
I wrote the parameter like that:
void Function(const char *v[])
Riccardo
But It doesn't work
Riccardo
I tryed with const char **v[] as parameter and then wrote &v when calling the function
Riccardo
But It doesnt work either

arrays are pointers
BinaryByter
hope that answers your question
Avezy
Yes
BinaryByter
passing a pointer as reference defeats the purpose

#include<stdio.h>
union complex
{
int rel ,img ;
};
void main()
{
union complex a,b,c;
printf("Enter realpart and imaginarypart of complex number a \n");
scanf("%d %d", &a.rel,&a.img);
printf("Enter realpart and imaginarypart of complex number b \n");
scanf("%d %d", &b.rel,&b.img);
c.rel = a.rel + b.rel;
c.img = a.img + b.img;
if(c.img>=0)
printf("sum of complex numbebrs %d + %di. \n",c.rel,c.img);
else
printf("sum of complex numbers %d %di \n",c.rel,c.img);
c.rel= a.rel*b.rel - a.img*b.img;
c.img= a.rel*b.img + b.rel*a.img;
if(c.img>=0)
printf("mul of complex numbebrs %d + %di",c.rel,c.img);
else
printf("mul of complex numbers %d %di",c.rel,c.img);
}
BinaryByter
use a struct, not a union
BinaryByter
they are fundamentally different

I wrote the parameter like that:
void Function(const char *v[])
Arrays are not pointers, but for function the following applies
any parameter of array type is adjusted to the corresponding pointer type
So you will never pass an array by value, the pointer to the first element is passed by value instead (which is like passing the array by reference).
So to pass your char *v[15] you probably want to write eithervoid foo(char** p) or void Foo(char *p[]), which is exactly the same because of the adjusting above.

To further answer your question, can you share your code please?

Yeah i know

google what an union is

but I also want to know why it was like that

Sorry i made a mistake in another part of the code the first method was working and now everything is fine

okay

It does not work since img will always be the same as rel. In fact you are only storing a single value and not two. As @linuxer4fun mentioned you should use a struct instead. A union can at any time store exactly one of the values

I think C programming

but c/c++ is pretty good too

but C++ does everything

so use that

C++ is the best one

We use other languages cuz they are easy

Guys check out my GitHub cpp programs.

It consists of some basic required programs in c++ along with some algorithms and data structures.
You can contribute to this repo, it's public and open source
Thank you

I don't think that's right. If you want to develop a prototype of any software, C++ might be Overkill. If you want to teach functional programming, you might better chose different languages.
In terms of efficiency, C++ is more efficient than most other languages, but does the customer really care if your, let's say Spotify client is written in C++ and performs 5% faster? The company developing such software does not and the majority of users does neither.
In my opinion something can't be best in in each aspect, which every advantages there are disadvantages

What's the difference between C++ and other languages?
I don't mean the syntax
The only difference between C++ and other languages is their API

That's still my opinion also

Exactly, some languages offer ABI compatibility, making it really easy to use third-party libraries without the need of recompiling millions of lines.
MᏫᎻᎯᎷᎷᎬᎠ
We can say
Other Languages = C++ libraries + API
BinaryByter
What other Languages have and C++ don't?
libraries, paradygms, better compatibility, better standard libary
BinaryByter
there is a HUGE lot
