6-4.c

好东西,绝对是好东西,我向大家推荐

#include <stdio.h>
int main()
{
	long i,k,j,a[80],b[80],c[80];
	for(i=0;i<6;i++)
	{scanf("%d %d",&a[i],&b[i]);}
	for(k=0;k<6;k++)
	{
		i=0;
		if(a[k]==0)
		printf("0");		
		{while(a[k]!=0)
		{
			c[i]=a[k]%b[k];
			switch(c[i])
			{
				case 10:c[i]+=7;break;
				case 11:c[i]+=7;break;
				case 12:c[i]+=7;break;
				case 13:c[i]+=7;break;
				case 14:c[i]+=7;break;
				case 15:c[i]+=7;break;
			}
			a[k]=a[k]/b[k];
			i++;
		}
		for(j=i-1;j>=0;j--)
		printf("%c",c[j]+48);
		printf("\n");}
	}	
	return(0);
}
