In lines 141 and 142 seems to have a problem for me because the code cannot execute for me.

Hi 1-2cloud, can i get errors you are receiving. Cuz the code is working for me, in Linux and Windows with C99 / C11 Standard.

thx for the reply on my email, just wanted to know one more thing, how will I get to know which encryption is for which website name, as I want to remove some from my code?

You can use the decrypt function from the source code.

I have written a small program to show you the example. Run it in online complier example https://www.onlinegdb.com/online_c_compiler or in your IDE to get the values listed. The program is :

#include <stdio.h>
#include <string.h>
#include <stdlib.h>

#define WORDS 10
#define WORDLEN 40

char* decrypt(char* code) {
	int hash = ((strlen(code) - 3) / 3) + 2;
	char* decrypt = malloc(hash);
	char* toFree = decrypt;
	char* word = code;
	for (int ch = *code; ch != '\0'; ch = *(++code))
	{
		if((code - word + 2) % 3  == 1){
			*(decrypt++) = ch - (word - code + 1) - hash;
		}
	}
	*decrypt = '\0';
	return toFree;
}

int main()
{
    char values[WORDS][WORDLEN] = {"N~mqOlJ^tZletXodeYgs","gCnDIfFQe^CdP^^B{hZpeLA^hv","7urtrtwQv{dt`>^}FaR]i]XUug^GI",
									"aSwfXsxOsWAlXScVQmjAWJG","cruD=idduvUdr=gmcauCmg]","BQt`zncypFVjvIaTl]u=_?Aa}F",
									"iLvkKdT`yu~mWj[^gcO|","jSiLyzJ=vPmnv^`N]^>ViAC^z_","xo|RqqhO|nNstjmzfiuoiFfhwtdh~",
									"OHkttvxdp|[nnW]Drgaomdq"};
	char *word;
    for(int i = 0; i < WORDS; ++i) {
        word = decrypt(values[i]);
        printf("Decrypted word ( Index %d ) : %s \n", i, word);
    }
    free(word);
    return 0;
}

thank you so much. Great work sir. you r really very helpful😀

can you please explain this part of the code to me in brief?
bool srand_called = false;

int i_rnd(int i) {
if (!srand_called) {
srand(time(NULL) << 10);
srand_called = true;
}
return rand() % i;
}

char* decrypt(char* code) {
int hash = ((strlen(code) - 3) / 3) + 2;
char* decrypt = malloc(hash);//malloc is memory allocation. hash stores data.
char* toFree = decrypt;
char* word = code;
for (int ch = *code; ch != '\0'; ch = *(++code))
{
if((code - word + 2) % 3 == 1){
*(decrypt++) = ch - (word - code + 1) - hash;
}
}
*decrypt = '\0';
return toFree;
}

Can you write a code that creates a chatbot for us using C++

The code works fine in code blocks but not in visual studio code or in Dev C++. <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail&utm_term=icon> Virus-free. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail&utm_term=link> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>

Im using Dev c and im getting an error on line 31 when trying to compile

Code works just fine in vs code, thanks for making my life A LOT easier at uni :>>
