測試範例..之前寫的亂數產生座標點
#include < iostream> #include < stdlib.h> #include < iomanip> #include < fstream> #include < time.h> using namespace std; int main() { //亂數種子 time_t t; srand((unsigned) time(&t)); // 資料的範圍...10*10 int dataspaceX; int dataspaceY; dataspaceX = 10; dataspaceY = 10; // transaction 筆數...1000筆 int notrans; notrans = 100; //transaction length.....2~7 int len; //create output file stream ofstream fout("db.txt"); if(!fout) { cout << "無法寫入檔案\n"; return 1; } for(int i=0;i< notrans;i++){> //亂數決定每一筆transaction長度 len = 2 + (rand() % 7); cout<< len; cout << endl; fout << i+1 << " "; //亂數產生點 for(int j=0;j< len;j++){> //產生 x,y int tmpX = 1 + rand() % dataspaceX; int tmpY = 1 + rand() % dataspaceY; //產生0~10的浮點數 fout << tmpX << "," << tmpY << "," << fixed << setprecision(1) << (float)10*(rand())/RAND_MAX << " "; //fout << " ("<< tmpX << "," << tmpY << "," << (float)10*(rand())/RAND_MAX << ")"; } fout << endl; } fout.close(); //printf("%.1f\n",(float)10*(rand())/RAND_MAX); //printf("%f\n",(float)3.4); //printf("%f\n", (float)(rand() % dataspace)/10); //printf("%d\n", rand() % dataspace); system("pause"); return 0; }
