Hi

Vidhya

Where static functions address stored in c?

Surya

@JRandomGuy @das_3sz3tt Actually it's compiling for prototype only. And I was missing some setting in keil and had to move one defined array to .c file instead of .h..... these two were the reason for the problems. Thanks for help guys

What is the use of socket programming?

klimi

@K11M1

yes?

Hi. Did you use rsa algorithm c++?

klimi

who?

Adkhambek

who?

Hi. For example you

klimi

no i haven't used rsa algorithm c++... i don't even know what that is

Hi. Did you use rsa algorithm c++?

you might easily use cryptographic algorithms by LibreSSL. LibreSSL is developed in C, so it is easy to use in C, C++, Fortran, ...

or u can use OpenSSL suite for more crypt algo with complete wrapper, but i heard recently it has some flaw that vulnerable to attack by hacker

when i using smart-pointer

Anonymous

and I see a error about unique_ptr

Anonymous

/usr/include/c++/9/bits/unique_ptr.h:406:7: note: declared here 406 | unique_ptr(const unique_ptr&) = delete; | ^~~~~~~~~~

Hey guys. I need a help

Eugy🧸

This algorithm should do linear sorting of the array

Eugy🧸

But when I compile it, it give me casual numbers without sorting it

Hubert

This algorithm should do linear sorting of the array

lets try to put srand(time(NULL)) out of loop

Hubert

But when I compile it, it give me casual numbers without sorting it

and i think you're missing the "{ }" in line 16, right?

Eugy🧸

lets try to put srand(time(NULL)) out of loop

Thank you for your help. I really appreciate it. It's working!

Eugy🧸

and i think you're missing the "{ }" in line 16, right?

I using an online compilator that don't have need to open and close {}. My school have Dev C++ as compiler, it's so buggy

Hubert

you're welcome

/usr/include/c++/9/bits/unique_ptr.h:406:7: note: declared here 406 | unique_ptr(const unique_ptr&) = delete; | ^~~~~~~~~~

unique_ptr is not copyable

Artöm

Its C++ that allows not to have them, but better put them for readability. And devc++ is not a compiler

Hello guys,I need help with program on C. write a program that will open the text file given as the call argument (if not provided, the default file should be used). If the file is properly opened, its content should be thrown on the screen. All possible errors, i.e. related to opening, should be handled and closing and show the correct syntax for calling the program when the program is called without arguments.

mei

int main() { char ch, file_name[25]; FILE *fp; printf("Enter name of a file you wish to see\n"); gets(file_name); fp = fopen(file_name, "w"); // read mode if (fp == NULL) { perror("Error while opening the file.\n"); exit(EXIT_FAILURE); } printf("The contents of %s file are:\n", file_name); while((ch = fgetc(fp)) != EOF) printf("%c", ch); fclose(fp); return 0; }

You need to take file name from argv, not from console input

NXiss7

int main() { char ch, file_name[25]; FILE *fp; printf("Enter name of a file you wish to see\n"); gets(file_name); fp = fopen(file_name, "w"); // read mode if (fp == NULL) { perror("Error while opening the file.\n"); exit(EXIT_FAILURE); } printf("The contents of %s file are:\n", file_name); while((ch = fgetc(fp)) != EOF) printf("%c", ch); fclose(fp); return 0; }

Change signature of main to int main(int argc, char argv[])

NXiss7

Then program arguments will be passed in argv, number of args will be passed as argc.

mei

Thx,i’ll try

NXiss7

You're welcome.

This code is so much not good..

/usr/include/c++/9/bits/unique_ptr.h:406:7: note: declared here 406 | unique_ptr(const unique_ptr&) = delete; | ^~~~~~~~~~

That means that copy constructor is deleted => you cannot copy unique_ptr which should be obvious

could someone tell me why it doesnt sort? void sort_3_nums(int *a, int *b, int *c) { if (*a > *b) swap(a, b); if (*b > *c) swap(b, c); if (*a > *b) swap(a, b); } void swap(int *a, int *b) { *a = *a + *b; *b = *a - *b; *a = *a - *b; }
