No difference

#include<stdio.h> int main(int argc, char *argv[]) { int j=0,i=0,count=6; switch(3) { case 0: while(--count>0) { case 1: ++j; case 2: ++i; case 3: ; case 4: ; case 5: ; } } printf("%d\t %d",i,j); return 0; }

Why it prints 5 5 instead of 0 0

How am I supposed to send my code here . It keeps getting deleted

cosnt have to be before class keyword

Sorry?

cosnt have to be before class keyword

Please, what is the use of const keyword when we declare a class in C++ ?

Instead of “class dynamic const” you should write “const dynamic class“

Please, what is the use of const keyword when we declare a class in C++ ?

for classes const have not any meaning

Hello

what is difference between a reference and pointer?

bruh I was just checking if it isn’t a spambot

// dynamic constructor #include <stdio.h> #include <conio.h> #include <iostream> using namespace std; class dynamic const { char *name; int size; public: dynamic const() { name = NULL; size = 0; } dynamic const(char *s) { size = strlen(s); name = new char(size) + 1; strcpy = (name, s); } void showdata() { cout << "name = " << name; cout << "size =" << size; } dynamic concat(dynamic const s2) { dynamic const temp; temp.size = size + s2.size; temp . name + new char(temp.size) + 1; strcpy(temp . name); strcat(temp . name, s2 . name); return (temp); } }; void main() { dynamic const s1("axxxan"); dynamic const s2("computer"); dynamic const s3(); s1.showdata(); s2.showdata(); s3 = s1.concat(s2); cout << "the concated objs are: "; s3.showdata(); getch(); }

Oh my, this is cursed :) case doesn't create scope (it is just goto under the hood), so it seems that this somehow jumps into the middle of the loop https://wandbox.org/permlink/SK6ELJZG7pHthpRj

You use windows? GTK better for linux apps

Don't use garbage. Use qt and everything will be okay.

What century now? Why we still using gtk?

What century now? Why we still using gtk?

:V but it doesn't work with C

I don't see a reasons to use gtk when qt available

I need to use C because it's the language the professor is using in college

my program only works when it's in the same directory of the dll files it needs

If you want one binary file(.exe) then use static linking

but if I use dynamic linking then my .exe has to be in the same dir as the dlls? Or can I change it?

Yes. But you can change it

I would have to change things inside the dlls?
