程序设计比赛较为实用的一些代码,希望对别人能有帮助

#include "iostream.h"
#include "stdlib.h"
int main(int argc, char* argv[])
{   
	int num;
	cout<<"\nF表硬币正面，B表硬币反面\n";
	while(cin>>num)
	{
	 int b=0,f=0,i;
	 for(i=0;i<num;i++)
	 {
	  if (rand()%2==0) {cout<<"B";b++;}
	  else {cout<<"F";f++;}
	  if ((b+f)%50==0) cout<<endl;
	 }
     
	 cout<<"\nB="<<b<<" F="<<f<<endl;

	}
	return 0;
