can somebody tell me , what does it mean?

for(int i=1;i<=n;++i,a=b){ cin>>b; if(a==b){ r=i-1; if(l==1) l=i;

This code through error??

can somebody tell me , what does it mean?

i cant understand a=b meaning here

Nothing

You know how on every loop i increments right? In every loop a is also resigned into b as well

Can you please elaborate..

The code means nothing, what else do you need to hear?

What matters is thinking

In fact, I prefer to be taught how to think rather than how to code

How to think like a programmer

How to think like a programmer

Author?

Its actually "think like a programmer" by v.anton spraul

Would it be beneficial to read this?

Assuming ur familiar with it since ur in this group

Hi guys, I'm writing two softwares, the former a Server program, the latter a Client program in Unix environment (using C). The client program uses a named PIPE (that is, a FIFO) in order to "talk" to the Server program. This one uses the FIFO on the "reading side". The problem is, I think I have to do something with the stdin in order to make every input from the client program go directly into the PIPE, thus for the server program reading it directly from the other edge of the FIFO, am I wrong? I mean, I wrote: close(0) (which is stdin); dup(FIFO_fd); (where int FIFO_fd= open(FIFO_NAME, O_RDONLY); But I don't know if I am doing it correctly. Since I closed the 0 entry in the process descriptor table, the dup operation should "allocate" the duplicated channel (that is, FIFO_fd) to the first available entry in the table, which is the 0. Thus the question: do I really need to do this? Or is it enough to open a FIFO on both Server and Client program and they'll talk automatically? Thanks!

Hi friend , i sent a message before you , my problem is like you can you help me ?

Maybe the factor is 4, so 32 to the array plus 4 to the float.

typedef struct{ char name[30]; float height; }person_s; Hello, Do you know why sizeof this struct is 36 not 40?

instead of printing in the console
