Basketball program

[noyd]

I recently had an extra credit problem for my c++ class. Although no one got it and its too late to hand it in, I would like to know how this program could be coded. Here it is:<br>
Have a user input the number of points they scored, then tell them how they could have scored those points. <br>
(using cout&lt;&lt;&quot;How many points: &quot;;<br>
cin&gt;&gt;score;<br>
<br>
Example:<br>
Enter the amount of points: 5<br>
You could have made a 3 point and a 2 point shot<br>
Or you could have made a 3 point shot and two free throws<br>
Or a two point shot and 3 free throws<br>
Or you could have made 5 free throws.<br>
There are three possible combinations<br>
:::::::::::::::::::::::::::::::::::::::::::::::::<br>
Please help if you can<br>
thanks

I haven't come upon a solution quite yet, but I have a feeling that a recursive function or two is going to be the key. The heart of the problem is a mathematical one. For starters, there are 5 possible combinations to the example you gave...<br>
<br>
1) 1 3ptr. + 1 2ptr. = 5pts.<br>
2) 1 3ptr. + 2 1ptrs. = 5pts.<br>
3) 2 2ptrs. + 1 1ptr. = 5pts.<br>
4) 1 2ptr. + 3 1ptrs. = 5pts.<br>
5) 5 1ptrs. = 5pts.<br>
<br>
Once the mathematics are straight, the coding itself shouldn't be too bad. I'll see what algorithms I can dig up.

This little box may make this hard to read but the code works. I used a form instead of cout...<br>
Let me know how it goes.<br>
<br>
D<br>
<br>
{<br>
int s;<br>
s=StrToInt(Form1-&gt;txtScore-&gt;Text);<br>
int a,b,c;<br>
a= s;<br>
b= s; //should be b=s div 2;<br>
c= s; //should be c=s div 3;<br>
int num=0;<br>
Form1-&gt;Memo1-&gt;Text=&quot;&quot;;<br>
for(int i=0;i&lt;=a;i++){<br>
for(int j=0;j&lt;=b;j++){<br>
for(int k=0;k&lt;=c;k++){<br>
if (i*1 + j * 2 + k * 3 == s){<br>
Form1-&gt;Memo1-&gt;Text= Form1-&gt;Memo1-&gt;Text + &quot;\r&quot; +<br>
i +&quot; Freethrows, &quot; + j + &quot; Twos, &quot; + k + &quot; Threes&quot;;<br>
num++;<br>
}<br>
<br>
}<br>
}<br>
}<br>
Form1-&gt;Memo1-&gt;Text= Form1-&gt;Memo1-&gt;Text + &quot;\r&quot; +<br>
&quot;There are &quot; + num +&quot; ways&quot;;<br>
}
