Rules should be any kind of picture is not allowed... Only screenshot is allowed... But only it was written pic of code is not allowed...so i didn't understood that part... Bcz rules are not clear... But before that only... Admin is talking so rudely...
Dima
be respectful, you came to this place asking OT questions, not c++ related

Where is the mute function
klimi
Here you go
Luca
hi guys
Dima
Welcome
Luca
int ricerca(int v1[], int v2[], bool sono_uguali, int n)
{
int i;
for (int i = 0; i < n; ++i)
{
sono_uguali = sono_uguali && (v1[i] == v2[i]);
}
return sono_uguali;
/* while(i<n && sono_uguali)
{

}

}
return sono_uguali;*/
}
int main()
{
int ar1[MAX], ar2[MAX], num;
bool flag;
int i=0;
printf("Inserire il numero di elementi\n");
scanf("%d", &num);
for(i=0; i<num; i++)
{
printf("Inserire ar1\n");
scanf("%d", &ar1[i]);
}
for(i=0; i<num; i++)
{
printf("Inserire ar2\n");
scanf("%d", &ar2[i]);
}
ricerca(ar1, ar2, flag, num);
if (flag)
{
printf("i valori corrispondono\n");
}else
{
printf("I valori non corrispondono\n");
}
return 0;
}
that's the code,
these are the errors:
p210n17.c: In function ‘main’:
p210n17.c:46:11: warning: passing argument 1 of ‘ricerca’ makes pointer from integer without a cast [-Wint-conversion]

what does it mean ç_ç
Luca
Basically i have to do a code where given 2 arrays i have to say with a boolean value if all the elements of the 2 arrays are equals or not.
Luca
oh
Luca
tryna fix
Luca
so how it would be?
Dima
I think you should replace this
for(i=0; i<num; i++);
{
ricerca(ar1[i], ar2[i], flag, num);
}
by this:
ricerca(ar1, ar2, flag, num);
Nils
Pointers are such a cool thing to mess with 😄
Nils
What if argv is not even used? Can I carelessly reuse that area?
Nils
Also would it make /proc/self/cmdline unusable?
Luca
I think you should replace this
for(i=0; i<num; i++);
{
ricerca(ar1[i], ar2[i], flag, num);
}
by this:
ricerca(ar1, ar2, flag, num);
now it says that the values aren't equal even if they are
Luca
yay
Artöm
Luca
now it's like it doesn't take the bool arg from the function wtf
code:
int ricerca(int v1[], int v2[], bool sono_uguali, int n);
int main()
{
int ar1[MAX], ar2[MAX], num;
bool flag=true;
int i=0;
printf("Inserire il numero di elementi\n");
scanf("%d", &num);
for(i=0; i<num; i++)
{
printf("Inserire ar1\n");
scanf("%d", &ar1[i]);
}
for(i=0; i<num; i++)
{
printf("Inserire ar2\n");
scanf("%d", &ar2[i]);
}
ricerca(ar1, ar2, flag, num);
if(!flag)
{
printf("I valori non corrispondono\n");
}else
{
printf("Tutti i valori corrispondono\n");
}
return 0;
}
int ricerca(int v1[], int v2[], bool sono_uguali, int n)
{
int i=0;
// int j=-1;
int j=0;
int s=0;
for(i=0;i<n-1;i++)
{
for(j=i+1;j<n;j++)
{
if(v1[i]>v1[j])
{
s=v1[i];
v1[i]=v1[j];
v1[j]=s;
}
}
}
j=0;
for(i=0;i<n-1;i++)
{
for(j=i+1;j<n;j++)
{
if(v2[i]>v2[j])
{
s=v2[i];
v2[i]=v2[j];
v2[j]=s;
}
}
}
for (int i = 0; i < n; i++)
{
if (v1[i] != v2[i])
{
printf("entrato per %d volte \n", i);
sono_uguali=false;
}
}
return sono_uguali;
}
Luca
when the program enters the last loop, it does the printf but the boolean value doesn't change, remaining on true ç_ç, so, when i go into the main it says that every value is equal even if not: it doesn't pass the boolean value. Already tried to declare the functions to boolean.

No, that area is usually allocated by calling process.
Edit: args passed into the stack.
klimi
You spam indeed

We should have banned you right when you joined
Techno
How can we create the GUI in C program ?
Mar!o
Win32 api 😂
Techno
Can u share a tutorial or something for ref
Mar!o
Just google C win32 tutorial
Techno
Can't we use QT framework ?
Techno
Or GTK ?
Nils
No, that area is usually allocated by calling process.
Edit: args passed into the stack.
So I can simply reuse it?
Techno
Oky thanks for help guys
NXiss7
So I can simply reuse it?
It's "read-only".
That's what const before char* means.
Nils
It's "read-only".
That's what const before char* means.
Hmm, I just tried and was able to successfully overwrite it with zeros
Nils
Nils
Can I somehow access that area as a variable that I can point my pointer to?
klimi
well
klimi
you have some function for alocating memory
Nils
Hmm, I could allocate additional memory but it does not look as clean to me.
NXiss7
NXiss7
Hmm, I could allocate additional memory but it does not look as clean to me.
No, learn RAII and dynamic memory.
Nils
Look, that is stack, you're writing data to your stack directly, without knowing sizes, that's a bad idea, you'll corrupt your memory.
Does not matter as I don't use variables anymore after having done that.
Nils
After that part only pointer stuff is following, then program exits
NXiss7
Nils
Okay... So I'd just allocate more memory.
NXiss7
After that part only pointer stuff is following, then program exits
Stack size is limited, and you don't control it directly.
When you create vars like "int a = 8" compiler pushes an sizeof(int) into stack.
Nils
What is it limited to?
NXiss7
If you're just playing around (which seems so) it's okay, I've done similiar things too, but just don't count on this coding style and read about memory management in C++.
Nils
Yeah I know 😅
Nils
If you're just playing around (which seems so) it's okay, I've done similiar things too, but just don't count on this coding style and read about memory management in C++.
Btw my goal is to convert brainfuck to C++ then excute is as native (and fast!) as possible.
klimi
do it with C
Nils
Why?
klimi
they are much closer languages
klimi
so you can convert branfuck -> C much very easy
Nils
Ah. But isn't C++ just an extension to C?
klimi
ye
klimi
but it has same security i think
NXiss7
What is it limited to?
It's influenced by lots of things, it's everything-dependent.
But consider it as few KBs to be safe, few MBs at most including all low level sruff, args etc to be more precise.
klimi
also c++ is not good for c++
Nils
