#include "stdio.h"
#include "stdio.h"
main()
{
int a,b,num1,num2,temp;
printf("please input two numbers:\n");
scanf("%d,%d",&num1,&num2);
if(num1)
{
temp=num1;
num1=num2;
num2=temp;
}
a=num1;b=num2;
while(b!=0)
{
temp=a%b;
a=b;
b=temp;
}
printf("gongyueshu:\n",a);
printf("gongbeishu:\n",num1*num2/a);
}
#include "stdio.h"
main()
{
int a,b,num1,num2,temp;
printf("please input two numbers:\n");
scanf("%d,%d",&num1,&num2);
if(num1)
{
temp=num1;
num1=num2;
num2=temp;
}
a=num1;b=num2;
while(b!=0)
{
temp=a%b;
a=b;
b=temp;
}
printf("gongyueshu:\n",a);
printf("gongbeishu:\n",num1*num2/a);
}
printf("gongyueshu:\n",a);
printf("gongbeishu:\n",num1*num2/a);
改为：
printf("gongyueshu:%d\n",a);
printf("gongbeishu:%d\n",num1*num2/a);
两个错误
1. scanf("%d,%d",&num1,&num2);中间多了个逗号，两个&d连续写
2. printf("gongyueshu:\n",a); 无任何变量输出，修改按一楼
另外if(num1)估计是搞错了，if (num1<num2)?
同二楼，但是if(num1)没有错，
if(num1)表示if(num1!=0)，防止除0错误，需保留。
