c语言求两个数之间的和跟差

Question

include <stdio.h">int fun(int a,int b, int *psub){ int sum; sum=a+b; _____①_____=a-b; return sum; }void main( ){ int x,y,s1,s2; scanf(“%d%d”, _____②_____); s1=fun(x,y, _____③_____); printf(“sum=%d\n sub=%d\n”, _____④_____); }用这种方法求的话，填空处怎么填啊，为什么我的总是报错

Answer 1

#include<stdio.h>

voidmain()

{

inta,b;

printf("请输入两个整数:");

scanf("%d%d",&a,&b);

printf("%d+%d=%d\t%d-%d=%d",a,b,a+b,a,b,a-b);

}

C语言求两个数的和差积商余数

#include"stdib.h"

#include"stdlib.h"

intmain()

{

intnum1,num2,a,b,c,e;

floatd;

printf("输入两个人整数：");

scanf("%d%d",&sum1,&sum2);

if(sum2==0){

a=num1+num2;

b=num1-num2;

c=num1*num2;

printf("和%d,差%d,积%d"，a,b,c);}

else(sum2!=0){

a=num1+num2;

b=num1-num2;

c=num1*num2;

d=num1/num2;

e=num1%num2;

printf("和%d,差%d,积%d,商%f,余数%d"a,b,c,d,e);}

system("pause");

return0;

}

Answer 2

#include <stdio.h>
int fun(int a,int b, int *psub)
{ 
int sum; sum=a+b;
  *psub = a-b; 
  return sum;
}
void main( )
{ 
int x,y,s1,s2; 
scanf("%d %d", &x, &y);
s1=fun(x,y, &s2);
    printf("sum=%d\nsub = %d\n", s1, s2);
}
//程序应该改成这样，该怎么填自己看下吧
