    Yahtzee C++ programme help

    hi all,
    i would like to make a yahtzee game but i would like some help to get it started i dont know where to start from??
    I would like to keep it simple and use the following:
    While loop
    For loop
    Arrays
    RAND_MAX
    rand()%n
    srand(seed)
    Re roll only once.
    The programme takes 5 input the 5 dices rolls and determines the 13 different outcomes possible scores. The programme inputs 5 values in the range from 1 to 6 abd stores the 5 values in an integer array. then determine the 13 alternatives then stores in a suitable array.

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

    int main()
    {

    You actually started quite well. Just write out the rest of what to do.

    Only thing to note is that, before rand() is called, make sure srand() is called. When you're testing, however, you may want to comment out the call to srand(). This allows your program to always have the same random numbers, so you can be sure your program works with the same set of numbers. After you're sure it appears to work, then you can add the call to srand() back in, and test your program with more random numbers.

    This is a school assignment, right? Considering the similarity with this thread: C++ removing cout ??

    I don't do other peoples homework, but I think the advice given in the other thread is suitable for you too.

    no its not for school just happens we share the same game?i dont want to use class, just simple loops and iterations will do.
    im retired, im an old man lol
    i just would like the code so i can Analise it and learn from it, please someone help me out?

    Either way, I'm NOT going to write the code for you. And I think I gave good advice in the other thread, if you care to read it.

    I presume you are doing this because you want to learn how to write programs, yes? And not because you have to, as you are retired.

    Then I don't really see the point in me (or anyone else on this forum) writing the code for you.

    It also seems like you are asking all over the place for this code - a google showed this up: http://news.devx.com/showthread.php?p=487283
    http://www.codeguru.com/forum/showthread.php?t=433070

    Both by someone called Kenneth_888. Maybe it's just a commen user-name?

    ive done this so far,
    but how do u keep the dice that i want and re roll the one i didnt keep?
    Code:
    #include <iostream>
    #include <cstdlib>
    #include <ctime>
    using namespace std;
    
    
    int main()
    {
     	int nums[5];
    	int i, j, input;
     
    	time_t t;
    	int count[6];
    
    	srand(time(&t)); /* seed the random number generator */
    	
    	for(j= 0; j < 14; j++)
    	{
    	for(i = 0; i < 5; i++)
      	{
        	nums[i] = rand()&#37;6 + 1;
        	cout << nums[i] << endl;
    		switch(nums[i])
    		{
    			case 1: ++count[0]; break;
    			case 2: ++count[1]; break;
    			case 3: ++count[2]; break;
    			case 4: ++count[3]; break;
    			case 5: ++count[4]; break;
    			case 6: ++count[5]; break;
    			default: cout << "An error has occured!"; break;
    		}
    	}
    	cout << "Choose which numbers you want to keep?( -1 to keep all numbers ) \n";
    	
    	
    	"\n";
    	cin >> input;
    	
        if(input == -1)
             break;
    	if (input > 6) cout << "Please select number from 1 to 6 only \n";
    	
    	'\n';
    	}
    	
    	if ( 
    	
    
      return 0; 
    }

    So, the array nums hold your current dice, right? Then you select one or more to roll again?

    In this case, you'll have to have an array of which dice to keep and which to roll again - and obviously just roll the ones that are listed as "roll again".

    I would also suggest that your move the counting of each digit to after you've rolled again.

    can u start me off ?? use switch statement?

    switch (keepRoll)
    case 1: if ( count[0] == input)
    ++count;

    Think about what you need it to do:
    You need an array of some sort to hold a list of which dies you keep (or which ones you roll). There are many solutions, but I don't see a switch being needed here.

    Code:
    '\n';
    While that's a valid statement, I doubt it does what you want it to. Put it in a cout.

    Code:
    srand(time(&t)); /* seed the random number generator */
    Since you're not using the variable t anywhere, just pass time() NULL and it won't use a variable.
    Code:
    srand(time(NULL));
    Code:
        	nums[i] = rand()&#37;6 + 1;
        	cout << nums[i] << endl;
    		switch(nums[i])
    		{
    			case 1: ++count[0]; break;
    			case 2: ++count[1]; break;
    			case 3: ++count[2]; break;
    			case 4: ++count[3]; break;
    			case 5: ++count[4]; break;
    			case 6: ++count[5]; break;
    			default: cout << "An error has occured!"; break;
    		}
    Why not this?
    Code:
        	nums[i] = rand()%6;
        	cout << nums[i] + 1 << endl;
        	++count[nums[i]];
    Code:
    if (
