U can read this code, first you read with //getchar();
after that u can remove commentline getchar();
And finally u can get it how it getchar function works

If you are using c++, then cin works well.

Good question, im using mac too.
I think the advantages of using mac are these:
battery time, portability,
operating system, trackpad
Mac os x more comfortable than Windows for a developer(i think)

Yess but some of developers says real developers dont use mac
Nool
No, not at all. If you are a good programmer, you know Unix.

We are thinking same pattern
Nool
That is enough.

Im worried about some software which i will not use in mac
Nool
Sometimes you have to pay for softwares in mac.
Nool
I think which is unnecessary.
Nool
That is I know, I said sometimes.

Do you know people here doesn't have to understand indian?
Francisco
I don't care, I don't understand neither of those, but I do understand English

Which is the main language in this group
Nool
Please don't make any assumptions, before you say something think about others. It's not your home.
Nool
Here, anyone can join group so you are nobody to comment on others language.

Oh boy it is written indeed

Hello, I'm Brazilian and I'm starting in C ++. I'm trying to create an array that already contains a certain value for all positions.
for example, an array of 500 positions where all elements are integer 0

Please, only English 🙂
Nool
Use memset
Francisco
Go to the pinned comment and read all the way through: "Only English language is allowed, if you speak shitty English or don't understand anything in English YOU WILL BE BANNED"

I don't believe that the menset works for me.

I think there is no better OS for programmers than Linux.

Real developers develop things that work. The rest is myth. The OS or compiler you use does not matter.

for (r = 0;r<=9;r++)
{
//USE inner loop
cout << "Enter details of Competitor " << r+1 << " ";
for(c=0;c<=1;c++)
{
cin >> sdata[r][c];
}
cout << endl;

Please can anyone explain why pressing spacebar allows the nested loop to proceed with the second cycle and not rather pressing enter.
Anonymous
Please I didn't get that
Anonymous
Well, not that there is a problem with the loop. That is only a fragment of an assignment which I am analysing and the instruction said that I should press spacebar after the first nested loop cycle and to my amazement, entering the next value assign it to the next array index but I rather expected an enter key to do the job.

So I am hoping that anyone can explain the reason behind what happened.

is malloc and new exactly same?
I have a class that the name is Entity
————————————
Entity * e = malloc(sizeof(Entity));
free(e);
————————————-
Entity * e = new Entity();
delete[] e;
What is the difference between them?
Sinan
Just "same" ? Can you open the subject a little more ?

In the first example, the malloc will not call ctor, it will just allocate the memory of size Entity. Free will just deallocate without calling dtor. However in second example the new will call ctor and delete will call dtor. The problem with ur code is "delete[]" is used for array. Since youre not allocating array at the time of new, so just "delete e;" is fine.

Okay got it. So if I had'nt used getchar in this program ,compiler would'nt executed the gets(c) statement . Can you explain why?
the last getchar() keeps your program waiting for an input after the computation is done. otherwise the program window would close after its work was done. this should be avoided because there are IDE project settings that can already stop the window from closing. further, these programs should be launched from a terminal instead of launched by double clicking.

I would have a question about C's realloc () function
I created an insertion function that fills an array based on double written in a file, so I don't immediately know how much memory to allocate, so I used an index and this increased in a while and continued to make a realloc () and in the meantime entered the new numbers in the file
If I print the vector in the function, however, it is fine .. while in the main, it prints all 0 .. does anyone know why?
Thanks
Mar!o
Pls share your Code

realloc can be tricky for beginners
