Question

求用C语言编写求两个数的和、差及平均值并输出 两个数要求是用键盘输入的任意两整数

Answer 1

任逍遥你的代码需要改下不然会出错。#include <stdio.h>

void main()
{
int x,y;
scanf("%d%d",&x,&y);
printf("sum = %d\n",x+y);
printf("%d\n",x-y);
printf("%f\n",(x+y)/2.0);//除以2可能产生小数，这点你得考虑
}

Answer 2

/* HELLO.C -- Hello, world */#include "stdio.h"
#include "conio.h"main()
{
int a,b,sum=0,avg=0,c=0;//定义变量，并赋初值
;
scanf("%d%d",&a,&b);//输入2个整数
sum=a+b;//求2数和
c=a-b;//求2数差
avg=sum/2;//求2数的平均值
printf("sum =%d\n",sum);//输出和
printf("c=%d\n",c);//输出差
printf("avg=%d\n",avg);//输出平均值 getch();
}//我用WIN_TC编译的，能成功得到

Answer 3

#include <stdio.h>

void main()
{
int x,y;
float ave;
scanf("%d%d",&x,&y);
ave=(x+y)/2;
printf("sum = %d\n",x+y);
printf("%d\n",x-y);
printf("%f",ave);
}

Answer 4

#include <stdio.h>

void main()
{
int x,y;
scanf("%d%d",&x,&y);
printf("sum = %d\n",x+y);
printf("%d\n",x-y);
printf("%d\n",(x+y)/2);
