趁著空檔簡單寫個測試亂數機率的程式
來個不傷腦力的這樣...
------------------------------------CODE------------------------------------
#include <cstdlib>
#include <iostream>
#include <time.h>
using namespace std;
int main(int argc, char *argv[])
{
int Cnt;
int Get;
int Box[9][2];
float Temp = 0;
srand(time(NULL));
for(int i=0; i<9; i++)
{
Box[i][0] = i+1;
Box[i][1] = 0;
}
cout << "實驗次數:";
cin >> Cnt;
for(int i=Cnt; i>0; i--)
{
Get = rand()%9+1;
Box[Get-1][1] = Box[Get-1][1]+1;
}
cout << endl;
cout << "數字\t次數\t機率" << endl;
for(int i=0; i<9; i++)
{
for(int j=0; j<2; j++)
{
cout << Box[i][j] << "\t" ;
}
Temp = Box[i][1];
cout << Temp / Cnt << endl;
}
system("PAUSE");
return EXIT_SUCCESS;
}

完畢,繼續唸書去...
