/*四则运算并计算其余数*/
#include<stdio.h>
int main(void)
{
    int num1,num2,sum,n,m,x;/*sum为两数之和，n为两数之差，m为两数之积，v为两数之商，x为余数*/
    double v;
    printf("Enter num1:");
    scanf("%d",&num1);
    printf("Enter num2:");
    scanf("%d",&num2);
    sum=num1+num2;
    printf("sum=%d\n",sum);
    n=num1-num2;
    printf("n=%d\n",n);
    m=num1*num2;
    printf("m=%d\n",m);
    v=num1*1.0/num2;/*乘上1.0，转变数的类型*/
    printf("v=%lf\n",v);
    x=num1%num2;
    printf("x=%d\n",x);
