  1. [source lang="cpp"]#include <stdio.h> #include <ctype.h> #include <stdlib.h> #include<conio.h> #include<iostream> struct list { int data; struct list *next; }*L; //function declaration: void create(int data,struct list **head); void print(struct list **head); int main() { //list *L; int data =10; for(int i=0;i<3;i++) { //struct list *pList = NULL; create(data++,&L); print(&L); getch(); } } void create(int data,list **head) { list *pNew = new list; if (*head==NULL) { (*head)->next=NULL; (*head)->data=data; //(**head).data=info; //pNew->data =data; //pNew->next=*head; } else { pNew =*head; while(pNew!=NULL) { //*head=(**head).next; pNew=pNew->next; } list *temp =new list; temp->data=data; temp->next=NULL; pNew->next =temp; //(**head).next=(**head).next; } //return 0; } void print(list **head) { list *temp1 = new list; temp1 =*head; while( temp1!=NULL ) { std::cout<< temp1->data<<" ";// show the data in the linked list temp1 = temp1->next; // tranfer the address of 'temp1->next' to 'temp1' } } [/source] Hello Guys, I am a bit rusty on pointers,i actually want to implement linked list ,but my compiler is giving error. i am getting run time error at line (head)->next=NULL; (head)->data=data; Would be great if someone can review the short snippet code and point my mistake. Any other suggestions are always welcome. Please note that i have also tried using (**head).data=data; but then also i am still getting runtime error . i am not sure how to proceeed next.
  2. Doubt regarding SDL programming

    Hi MaxFire, Thanks for the Information but i have already have a look at them and these things are not there.,but i gained all of knowledge from there. Can you please suggest some other good SDL programming sites esp related having motion and collision examples. Thanks Jatin
  3. Doubt regarding SDL programming

    Hi Guys, I am stuck again and need you help on two issues,if some one know any thing about these two things please reply 1)I want to create a negative of an image if say the user enter key 'N'.Now i know the logic of creating an negative ie find RGB value of each pixel on the screen,then subtract the indiviual RGB value from 255 to get the new value.However i do not know how can we take RGB value from each pixel and then write them back on screen.Have anyone tried something like this or do someone have a better idea.Please some reference code if some one has tried anything like this. 2)I am trying to create a camera in SDL by using SDL_rect and then positioning it in the screen by giving some offsets,but what i really want to achieve is that i have created an animation and i would like my camera to move along with it.I mean if my animation is moving to the right ,it should feel like camera is following him.But i am unable to achieve this result.Have anyone tried to emulate a camera in SDL before and if yes assist me.
  4. Doubt regarding SDL programming

    Hi All, I have a doubt regarding SDL programming. Can some one please help me how can i subdivide a Image lets say into 4 parts and then store them in SDL_Surface array. I intend to animate later using these subdivided images by using SDL_BlitSurface function. I am new to SDL,so it would be great if someone could provide some codes for reference. Please note that i am using Microsoft visual c++ 2010 compiler.. Thanks Jatin
  5. Help Needed in a C++ program

    Hi Cornstalk, Thanks for the information and more importantly correcting me about how to post effectively on Game dev,Well it was my first post and i think one mistake is fine..But will take care next time. Hi BeerNutts, Using khbit have solve my problem.Thanks a lot...Cheers @ ALL Can i ask one more doubt regarding this program here only or should i start a new thread. Actually i also want to include a timer in my program..to keep a track of how many correct random alphabets the user enters in say 60 secs.. I can you a variable and assign it value 60.and then decrease it by 1,but how to make sure that after exactly one sec it would get displayed in the screen. i.e i need to display the counter exactly after 1 sec and this should not affect my other program functioanality .Is this possible, there must be a solution.Guys please provide some pointers/suggestions regarding the same. Thanks Jatin
  6. Help Needed in a C++ program

    Hi, Actually i was not sure whether i should post this in beginner or game programming thread. That why posted there also.
  7. Help Needed in a C++ program

    Hi Everyone, I am Actually trying to make a simple C++ game in which some random alphabets will fall down and when we press one of those random alphabets keys the aphabet should disappear. The problem that i am facing in making this code is that when i am using some function to read the key input that causes my program to wait for the user's input and hence my program comes to a stop till i press some key. I want some logic/function which will stop the execution of my program. Can you please suggest any such function or some logic that i can use in this program. Please note my compiler is Microsoft Visual C++ 2010 and i am not that familiar with the functions in windows.h header file. Thanks in advance. Any pointers would be greatly appreciated. My program is somewhat like this /*Including Header Files*/ #define _CRT_SECURE_NO_DEPRECATE # include <iostream> # include <conio.h> # include <Windows.h> int i=0,y=1; char words[5]; int pos[5]; char c; void gotoxy(int x,int y); void Movement(); int readkey(void); void random() { int n; for (int t=0;t<5;++t) { n= rand() % 26; pos[t] = n % 2; words[t] = (char)(n+65); } } void main() { random(); for(y=0;y<10;y++) { for(i=0;i<5;++i) { gotoxy(3*i,pos[i]); printf("%c",words[i]); pos[i]=pos[i]+1; if(y>0) { gotoxy(3*i,pos[i]-2); printf("%c",' '); } } Sleep(1000); } getch(); } void gotoxy(int x,int y) { COORD coord; coord.X = x; coord.Y = y; SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), coord); } [img]index.php?app=core&module=task[/img]
