如何编写程序，输入俩个整数num1和num2，计算并输出它们的的和，差，积，商，与余数

编写程序有许多语言，假设是C语言吧

#include <stdio.h>

int main(int argc,char **argv)
{
int num1,num2;
int n1;/*和*/
int n2;/*差*/
int n3;/*积*/
int n4;/*商*/
int n5;/*余*/

printf("请输入整数num1=?");
scanf("%d",&num1);
printf("请输入整数num2=?");
scanf("%d",&num2);

n1 = num1 + num2;
n2 = num1 - num2;
n3 = num1 * num2;
n4 = num1 / num2;
n5 = num1 % num2;

printf("和=%d\n",n1);
printf("差=%d\n",n2);
printf("积=%d\n",n3);
printf("商=%d (整除商)\n",n4);
printf("商=%f (浮点商)\n",(double)(num1/num2));
printf("余=%d\n",n5);

}

#include<iostream>
using namespace std;
int main()
{
int num1,num2;
cout<<"输入两个整数:"<<endl;
cin>>num1>>num2;
cout
