自己写的关于求最大公约数的程序,我不知道错在哪了,求指点
int gcd(int a,int b){int x,y,r;
r=x%y;
if(r=0)
return x;
else
{x=y;
y=r;
gcd(x,y);}
}
void main()
{int a,b;
scanf("%d,%d",&a,&b);
if(a>b)
printf("gcd=%d",gcd(a,b));
else
printf("gcd=%d",gcd(b,a));
}
程序代码:#include "stdio.h"
void main()
{
int a ,b,num1,num2,temp;
printf("please input two number:\n");
scanf("%d%d",&num1,&num2);
if(num1<num2)
{
temp=num1;
num1=num2;
num2=temp;
}
a=num1;
b=num2;
while(b!=0) /*辗除法*/
{
temp=a%b;
a=b;
b=temp;
}
printf("gongyueshu:%d\n",a);
printf("gongbeishu:%d\n",num1*num2/a);
}你可以参考下,
