C :: Time Scheduling Algorithms Program
Jan 20, 2014I am an IT college student and this is a self-assigned project i have done in an attempt to learn programming in C AND at the same time how time scheduling of an OS works (Both done in order to prepare for upcoming semester exams) using FCFS ,SJF, RR and PS algorithms (planning on adding SRT too sometime soon). (took me 9 hours total work time including validations). What i wanna know is from more seasoned coders if i am on the right track. *cross fingers*

#include <stdio.h>
#include <stdlib.h>
#define P_Q 1000

Jan 30, 2014I am trying to count the number of comparisons for each of the following sorting algorithms, Selection, Insertion, Bubble, Merge, and Quick sort. This is using an array of numbers that are sorted, reversed, and randomly arranged.
I currently increment the "number of comparison" variable before every conditional statement that compares two numbers and am getting the following results:
Number of Items in Array = 100
Selection: random = 5049; reverse = 5049; sorted = 5049;
Insertion: random = 2640; reverse = 5049; sorted = 99;
Bubble: random = 9207; reverse = 9900; sorted = 99;
Merge: random = 1221; revere = 988; sorted = 1028;
Quick: random = 690; revere = 587; sorted = 636;

Dec 25, 2014I am working on a script compiler that must output compiled script into binary file. Compiling etc is not a problem. The problem is detecting some specific cases. Nothing seems to work. If it works, then it breaks as soon as i modify the script.
Here is example "script1":
Code:
1VAR1 c1 = 44
2VAR2 c2 = 66
3beginscript
4if(c1=44)
5do_nothing
[Code] ....
Second example "script2", when there can be also some command between ENDIF and ENDIF. In this case: do_nothing command.
Code:
1VAR1 c1 = 44
2VAR2 c2 = 66
3beginscript
4if(c1=44)
5do_nothing
[Code] ....
The INDEXES before each line are not in actual script. They are just to point YOU to specific lines. Although the INDEXes are in compiled script!! This is very important. As you see there can be simple IF_ENDIF and nested (more complex) IF_ENDIF.
i.e IF_ENDIF inside another IF_ENDIF.
There are also IF_ELSE_ENDIF and some other ones, but im trying to make simple IF_ENDIF work first.
ENDIF is "SPECIAL" command, the IF, DO_NOTHING are "usual" commands.
"Usual" commands must always jump over(!) the ENDIF. ALWAYS!!
They must "ignore" them!
One strong RULE is like this for usual commands: always jump over any ENDIF, not matter what. If there is one, two or more ENDIF's in a row, then just jump over them to the closest NEXT usual block command. If there is some "usual" block command between multiple ENDIFs, then jump to this command and this command must therefore check whats next command right after it. And do the same: check if next command is ENDIF, if yes, jump over it, until "usual" block command is found.
This is the place im stuck. When i some time ago thinked about some ideas, i saw some patterns. One of them was that: Seems like if its nested IF_ENDIF, then every usual block command jumps out of it, i.e. right after the final ENDIF of this current nested IF_ENDIF.
But as soon as i added do_nothing between the two ENDIFs the so called "pattern" broke. In script2 above you see index 11 is do_nothing. Ok its in nested IF_ENDIF it should jump out to command index 17. But no, because there is do_nothing between index 13 and 16. If we jump out at index 11, the command 14 would never execute. This is a BIG NO. One idea i was thinking and trying was to use STL::FIND, STL::FIND_IF to find next "usual" command after specific index. But my code seems to crash sometimes and not work always.
Code:
bool NextNonENDIF(int i) {
return (i!=98);
}
int findNextBlockCmd(vector<int>&vec, int curidx)
[Code] ....
Here i pass him the vector that contains all the command TYPES in current script. Each command has its own TYPE or better called unique ID in which way compiler knows what is what. So in this case im trying to find a command thats NOT "ENDIF", in other words im trying to find next usual command after specific type of command. Lets just say the TYPE or unique ID of do_nothing is 555, im trying to find it.
How i should continue with this? What to use maybe stl::stack, some custom command indexing, some sort of labelling for usual commands in nested IF_ENDIFs or what?
In general, look script2, and i ask: There is index 11, this guy should look if there is any usual block command left for him before the final ENDIF at index 16. If there is, jump to it. If there is none, jump out of this nested IF_ENDIF to index 17.
Question: how to do it? What algorithms to use? I can use STL, BOOST, whatever. And i can use C++11.

View 2 Replies View RelatedC++ :: SDL Rotating Images Function
Jun 9, 2013Since SDL doesn't have it's own function for rotating images and I'm tired of storing multiple angles of the same sprite in a file, I created my own function for doing so:
//XY Class
class XY {
public:
XY(){}
XY(float x, float y);
[Code] ....
The problem is while Spin does spin the surface correctly, some pixels are rotated to the same new position so gaps appear in the returned surface. I need a way of filling in the gaps so the returned image looks better. A link to a program I made that uses this function is below so you can see the problem that I'm talking about. [URL] ....
I currently use SDL 1.2. Could my problem be fixed if I used 2.0? For example, does SDL 2.0 have a built in function for rotating surfaces?

C++ :: Compile Images (PNG Files) Into Application
Jun 19, 2014I am currently coding a 2D game in Visual Studio 2013. All of the .png graphics are saved in an absolute directory (for example, "C:/gfx/example.png"). Although this works for testing the application on my own system, I would one day like to release it (although it won't be commercial, as I am just learning). I could put all the of the image files in a relative folder, but I do not like the idea of my graphics being out in the open like that.
Is it possible to compile these images into the application itself? I had been researching resource files on Google, but I am still not completely sure if this is what I need to be using. Even if it is, I am using the express version of VS, so I do not have access to the editor. If resource files are what I am looking for, do I have to purchase an upgraded version of Visual Studio, or can I use another editor?
