C语言求余数

#include
void main()
{
float num,num2;
printf("Please input two number:");
scanf("%f%f",&num,&num2);
printf("num+num2=%2f\n",num+num2);
printf("num+num2=%2f\n",num-num2);
printf("num+num2=%2f\n",num*num2);
printf("num+num2=%2f\n",num/num2);
printf("num+num2=%2f\n",(int)num%(int)num2);
getch();
}
算不出余数 求教

我用的事winTX编程 结尾必须有getch()

#include
#include
void main()
{
int num,num2;//这里改了
printf("Please input two number:");
scanf("%d%d",&num,&num2);
printf("num+num2=%2d\n",num+num2);//下面的都改了
printf("num+num2=%2d\n",num-num2);
printf("num+num2=%2d\n",num*num2);
printf("num+num2=%2d\n",num/num2);
printf("num+num2=%2d\n",(int)num%(int)num2);
system("pause");
}

如果一定要用浮点数：

#include
void main()
{
float num,num2;
printf("Please input two number:");
scanf("%f%f",&num,&num2);
printf("num+num2=%2f\n",num+num2);
printf("num+num2=%2f\n",num-num2);
printf("num+num2=%2f\n",num*num2);
printf("num+num2=%2f\n",num/num2);
printf("num+num2=%2d\n",(int)num%(int)num2);//改这里
getch();
}

你写了两次输入。。。 scanf getch 你的这个getch是什么意思呢？

余数是整型的， 输出用 %d 不能用 %f

printf("num+num2=%2f\n",(int)num%(int)num2);%2f改成%2d, 算没错, 是打印结果时有问题.
