rand生成随机数据
跑了N多数据,还是没有找出错误点。。。。。。。。。。。。fuck
#include <iostream> #include <ctime> #include <cstdio> #include <windows.h> using namespace std; int main() { while(1) { FILE *fp; fp = fopen("E:\\ACM\\POJ\\poj_3176\\in.txt","w"); int n; srand(time(NULL)); n = rand()%100; fprintf(fp,"%d\n",n); for(int i=1;i<=n;i++) { for(int j=1;j<=i;j++) { fprintf(fp,"%d ",rand() % 100); } fprintf(fp,"\n"); } fclose(fp); Sleep(5000); system("type in.txt"); system("type.bat"); } return 0; }
Keep it simple!
