编写程序,从键盘输入两个整数给a和b,求他们的和,差,商数和余数,并输出结果

Question

要过程

Answer 1

#include <stdio.h>

int main()
{
int a,b;
printf("Input a, b: \n");
scanf("%d %d",&a,&b);
printf("a + b =: %d\n",a+b);
printf("a - b =: %d\n",a-b);
printf("a * b =: %d\n",a*b);
printf("a / b =: %d\n",a/b);
printf("a %% b =: %d\n",a%b); //余
return 0;

}

结果：
Input a, b:
9 5
a + b =: 14
a - b =: 4
a * b =: 45
a / b =: 1
a % b =: 4

Answer 2

#include<stdio.h>
void main()
{
int a,b,m,n,p,q;
scanf("%d%d",&a,&b);
m=a-b;
n=a+b;
p=a/b;
q=a%b;
printf("%d\n",m);
printf("%d\n",n);
printf("%d\n",p);
printf("%d\n",q);
}
}
