b.cpp

这是基于密码学的几个编程,很基础,但却是密码学中常用到的

#include <stdio.h>
//#include <stdio.h>
main()
{
	int a , r, b;
	scanf("%d",&a);
	int Binary[10];
	int i = 0;
	do
	{
		b = a / 2;
		r = a % 2;
		Binary[i] = r;
		i ++;
		a = b;
	}
	while( a != 0 );
	for(int j = i - 1 ; j >= 0; j--)
	{
		printf("%d ", Binary[j]);
	}
}
