What is random?

[Maza Ron]

Need someone to help me..
need examples..

[Azagaros]

Have you ever looked up the word random in the dictionary?

If you need it in terms of c++? This is a good place to start:
http://www.cplusplus.com/reference/clibrary/cstdlib/rand/

If you want to incorporate randomness into a programming environment, use the include header, if using C++, called -->> "time.h" << -- . If you don't know about it it's very simple. You seed the random integer/etc. using -->> srand(time(0)); <<-- and then a switch statement usually handles the rest. I think this site helps with that certain problem though.

If you want specific help from me about it just ask.

can look up into this question?

[Azagaros]

this is homework. What do you have so far?

[Maza Ron]

#include <iostream.h>
#include <stdlib.h>
#include <conio.h>

void main()
{
int movement, forward, backward;
srand((unsigned)time(NULL));

for(int i=0;i<10;i++)
{
movement = rand()%2;
cout << "Movement : " << movement << endl;





\\ this so far...

[Maza Ron]

need help....really blurr right now..

[Azagaros]

if I generate 0 or 1 for movement how are they interpreted? this is an if statement to me. How are you tracking the ant's position? I don't care about backwards or forwards from your code, unless I am counting them. The problem on the web site you gave didn't indicate you needed to.

[Maza Ron]

mybe need to set default on 4.....the step could be more than 9! mybe up to 60 step....
the 0 will be the forward movement
the 1 will be the backward movement....

i can do only on the previous code i posted

[Azagaros]

Does your problem have a default value for the ant's position? I would have to look again to it.
so if I am given what you have so far?

#include <iostream>
#include <cstdlib>
using namespace std;

int main()
{
     int antPosition = 4;  // ant's default position.
     int steps = 0; // the steps counter...
     int movement = 0; // the movement direction indicator
     srand((unsigned)time(NULL));

     for(steps = 0; steps < 10; steps++)
     {
            // dump out the two lines of the fancy graph... 
            // the top bar of each row and the middle line
            // this can be done in another for loop.
           // there will be an if the counter of the for is equal to the ants position.
           
           // now we do a movement 
           movement = rand()%2;
           if(movement == 1) // we will move foward
           {
                  antPosition++; // forward we increment the ants position
            }      
            else // we will move back wards.
            {
                  antPosition--;  // backwards we decrease the ants position
            }
  
            // I will want to make sure the ant is still in bounds for our move
            // this will be an if of antPosition for the ranges give in your problem
            // if we are out of bounds we reset to the upper or lower limit.

     } // the end of the for loop.

     // now dump out the bottom bar of the graph using another for loop.
     return 0;
}// end of main

how about the boxes...the question 2 is the next page of the homework..it show the sample output...have u seen it?

[Maza Ron]

problem....my c++ builder is borland...is it the code same? because i cannot run the program...

[Azagaros]

Yes I have seen it, its pretty easy for me a 20 years of c++. If you read the comments up there I give you in a previous one it tells you a little bit about how to do it.

for example:

// dump out the two lines of the fancy graph... 
// the top bar of each row and the middle line
// this can be done in another for loop.
// there will be an if the counter of the for is equal to the ants position.
// dump out the header line header
// start with the step count box.
cout << "+-----------+";
// loop through to create the cap of the other boxes.  I don't know if I have the count right.
for(int nIndex =0; nIndex < 9; nIndex ++)
{
      cout << "-------+";
}
// once the line is complete dump a endl for the new line.
cout << endl;

// print out the first part of the step line.  I would have to work at it to make it line up
cout << "| Step #" << steps << " |";

// the rest here looks simalar to what is before this but I need to test for the antPosition against nIndex if I use the variable again.

I am not responding to anymore.. You need to figure this out on your own. I think I have given you most of what you need to finish the program. I have given you all the clues in all the code segments in the code. Most of this should compile on a standard c++ compiler, which borland c++ build is.

The original code I gave you had no output lines so if it ran you wouldn't see anything output.
did you create a console application?

Thank you very much..=)
