编写程序,求两个实数(定义变量 double x,y;)的乘积和商

#includemain(){floata,b,c;scanf("%f%f",&a,&b);c=a+b;printf("%.2f\n",c);}

voidswap(int*x,int*y){inttmp=*x;*x=*y;*y=tmp;}

#include"stdio.h"voidfunc(inta,intb,int*he,int*ji){      &nb

#includeintgongyue(intm,intn){intr;if(m==n)returnm;elsewhile((r=m%n)!=0){m=n;n=r;}returnn;}voidmain(

#includeintmain(){chara,b;a=getchar();scanf("%c",&b);printf("a=%c\n",a);printf("b=%c\n",b);return0;}

也没说用啥语言,用C语言写了#include#definePI3.1415926intmain(void){floatr=0.0;floats=0.0;printf("Pleaseinputthera

#includeintmain(){intm,n;do{printf("输入两个非零整数:\n");scanf("%d%d",&m,&n);}while(m==0||n==0);printf("%d+

程序用什么语言?“writeln(a:5,b:5)”是以场宽5输出a、b的意思.

intk,m,n;m=1;n=2;k=m;m=n;n=k;再问：要完整版的。。。再问：要完整版的。。。再答：你不会是在考试吧？#includevoidmain(){inta,b,k;printf("请

你这个问题也太简单了吧,看来你是初学者：#includevoidmain(){inta,b,t;scanf("%d%d",&a,&b);t=a;a=b;b=t;printf("\n%d%d\n",a,

#includevoidmain(){floata,b,result;charc;printf("pleaseinputastatement:");scanf("%f%c%f",&a,&c,&b);s

这个可以这样做~cleara=rand(10,1);%产生一组随机数b=rand(10,1);%产生另一组随机数b=b-(dot(a,b)/dot(a,a)).*a;%可以使用施密特正交化的方法转化d

#include"stdio.h"intsum(inta,intb){returna+b;}voidmain(){inta=3;intb=5;printf("%d",sum(a,b));}

//#include"stdafx.h"//vc++6.0加上这一行.#include"stdio.h"intn=-9;doublef=1.0;voidmain(void){intm=-n+1;for

#includemain(){charx,y,z;printf("请输入两个字符：");scanf("%c%c",&x,&y);z=x;x=y;y=z;//交换成功.}
