Mar 5, 2013You are programming a sideways scrolling shooter. This used 2D cell based maps that are very long (over 100,000 characters per row long, 24 rows of 40 characters on screen), and the only way you can get them to fit in memory is to compress each row of the map using run length encoding and to decompress each new column of the map on the right of the screen as the background moves from right to left. You maintain a list of pointers into the RLE data for each row of the screen. Columns that are scrolled off the left are discarded. This works very well and the game only just fits in the available memory. Suddenly the game designer decides that the game should also be able to scroll from left to right at any point, and for any duration. Stunned and dismayed, you explain to him that RLE compression only works in one direction, but he’s adamant. Figure out a way of doing what he wants without using much (no more that 1K of) extra memory. Explain the algorithm used for decompressing in both directions. (assume the RLE algorithm used is: a positive byte N followed by a byte B, indicates a run of N copies of B, a negative byte -N followed by N bytes indicates that those bytes should be copied directly. For example, the sequence 2,2,2,2,5,1,2,9,9,9,9,9 would be coded 4,2, -3,5,1,2, 5,9.)
how can I compress the information? My first thought was making a change to the RLE compression but i gave up on that thinking it wasn't possible.
C++ :: How To Move A Ball Continuously In 2D Scrolling Game
Dec 29, 2013The situation is , I have a ball which should move on a flat horizontal surface which i have created in a display of 800 x 400 . Right now!I am able to make it move left or right in direction using key inputs at a fixed speed.
But I want to make it move horizontally at a constant velocity without using keys. Like in copter game.
It should be able to move automatically , towards the right side.
Increment x position by speed variable does the trick but When I used it with keys I used to limit the movement like.
ball.x += ball.speed;
if(ball.x > 750)
ball.x = 750; // because my screen width is 800.
[URL] .... < this video will show what I really want to do with the ball
If you saw the game video in the link i gave, the ball kept moving with constant velocity. But it never went out of bound. What is keeping it from not getting out of display screen. Instead! its moving continuously... but stays almost at the center of screen. How?

C :: Restrict Type Qualified Pointers
Sep 6, 2013I want to give a try to "restrict" type-qualifier. I have looked for examples on google and I see the format is used: "int * restrict p";
However when I write this I get an error: "p is undeclared"
I am using GNU GCC Compiler with Code::Blocks.
How can I solve this problem. Is it possible me to adapt the compiler to C99 standarts, if I can, will it solve my problem?
C++ :: Horizontal Scrolling ASCII Image - Hit Enter To Continue Or Esc To End
Sep 3, 2013I would like the coded ASCII image to scroll horizontally 3 times and then end with the message:
"Hit Enter to continue or Esc to end"
If Enter is pressed, the program should then continue to scroll another 3 times and then display the same message above.
If Esc is hit then the program loop should stop similar to an escape sequence.
Here is my code that partially accomplishes my objective:

C++ :: How To Restrict User To Enter Four Digit Number Only
Aug 22, 2014I am trying to write up something to have a user to enter a four digit number. Only four digits, Ex: 0001, 0116, or 9999. There is no getting around the selection 0001 or 0002. I understand if not done correctly, the first three 0's will be ignored.
I've been just playing around with what I have below but I just don't remember how to do it nor can I find a good example online to figure it out. I know it is not correct just typing to try to remember. I am aware that it is gibberish right now, this is just me brainstorming.
int number;
cout<<("Please enter the four digit number(Ex: 0001):
");
cin>> setw(2) >> number;
cout<<)"Please enter four digit date. Two digits for month and two digits for year:
");
cin>> date;
if (number< || number > 30)
cout << "Invalid choice. Try again." << endl;
cin.clear();

C++ :: Calculating With Time - Restrict User To Input Minutes 60-99 For Every Hour
Oct 22, 2013I have to write a program for class in which users will be inputting:
start time = startTime
number of minutes = callDuration
so first off, teacher wants us to input time as a floating point number such as 09.00
How do I validate the time so that users cant input i.e. 09.61 for every hour? In other words, so the user cant input minutes 60-99 for every hour.
then, when calculating:
endTime = startTime + callDuration
how would I make endTime display a correct time in such a situation: endTime = 09.45 + 00.30
so that it displays 10.15 not 09.75

C :: Write To Screen Lowest N
Oct 31, 2013My problem is :
Code: numbers[10]={25,27,17,19,47,3,98,5,124,10};
You write a program at do below processes for above array.
You want a number 1 between 10 at user.
if user enter N value,program write to screen lowest N. number at array. For example user enter 2,program write to screen lowest secondary number of 5 value at array or user enter 10 value,program write to screen maximum number of 124 value at array.
But write the program with don't use sorting algorithm.
C++ :: Clear Screen Without Blinking
Nov 4, 2013I have a one simple question :D. I want to output to the console some symbols. Let's say that i have a loop.
for(int i = 0; i < 10; i++) cou << "* ";
Then I want to output other symbols but I want to overwrite the previous symbols. I know I can use system("cls"); but it blinks if I try to output the same characters. For example if I have:
for(int i = 0; i < 10; i++) cou << "* ";
system("cls");
for(int i = 0; i < 10; i++) cou << "* ";
After I run this code the first loop outputs ten "*". Then there is a blink and there are again ten "*" shown. How can I avoid this blink?

C++ :: Clear Part Of The Screen?
Nov 3, 2014Is there any way I can clear only a selected part of the screen? (I'm aware of system("cls"))
For example, when you enter a date, and is wrong, could it just errase that input and only say "Wrong try again" without errasing everything else you where doing?
In this case, a function that only errases what is in the while
while(not wrong)
{
cout<<"DIA: ";
cin>>obj.dia;
cout<<"MES: ";
cin>>obj.mes;
cout<<"ANIO: ";
cin>>obj.anio;
}
PS: Also, is there any whay in which you can ask the user to enter the date DD/MM/YYY?

C++ :: Hold Screen Via GUI To Console
May 15, 2013I had a program (on console) that uses a third-part software to draw some graphs. In order to hold the graphs on the screen, I used cin.get(); and that worked.
Now I created a GUI with Qt. The code remains generally the same. The code continues to call the software to draw graphs (during drawing graphs, there is a console opened automatically). Butcin.get(); in the code cannot hold the graphs on screen anymore. The graphs appear and disappear immediately.
