Shell程序的一元二次方程-搜答案-拍题作业网

PrivateSubCommand1_Click()DimaAsSingle,bAsSingle,cAsSingleDimdAsSingle,x1AsSingle,x2AsSinglea=InputB

#include#includeintmain(void){inta,b,c;//定义一元二次方程的三个数值；printf("请依次输入一元二次方程的三个参数abc,中间以空格隔开\n");scanf

double x1 = 0;//解1double x2 = 0;//解2Console.WriteLine("求 ax^

#includeusingnamespacestd;intmain(){floata,b,c;cin>>a,b,c;if(b*b-4*a*c

#include#includeintmain(){inta,b,c,x,p,x1,x2;printf("输入三个实数：\n");scanf("%d%d%d",&a,&b,&c);p=b*b-4*a*

lf%错了,应该是%lf

修改如下：//---------------------------------------------------------------------------#include"stdio.h"#

#include"stdio.h"#include"math.h"doublex1,x2,p;floatfile1(floata,floatb){x1=(-b+sqrt(p))/2*a;x2=(-b-

#include#includevoidm(floata,floatb,floatc){\x09doublex1,x2;\x09x1=(-b+sqrt(b*b-4*a*c))/(2*a);\x09x2

#include;#include;#include;main(){floata,b,c,d,e,f;scanf("%f%f%f",&a,&b,&c);d=b*b-4*a*c;if(d>=0){e=(

#include"stdio.h"#include"math.h"voidmain(){floata,b,c;floatdelta;printf("inputa:");scanf("%f",&a);p

第二题：#includevoidmain(){inti,g,s,b;for(i=100;i

C++的代码：#include#includevoidmain(void){doublea,b,c,d;charch('y');do{coutb>>c;if(-0.0001

两处错误,第一个,没有赋值过程,应该改为：a=InputBox("a=")b=InputBox("b=")c=InputBox("c=")第二个：x1=(-b-d)/(2*a)应该是x2=(-b-d)

以下是画一元二次方程的图的代码：（假设y=a*x^2+b*x+c,将窗口的大小调为4800×4800）PrivateSubCommand1_Click()ClsLine(0,2400)-(4800,2

(1)输入a=2,b=3,c=-1;(2)dt=b^2-4*a*c;(3)如果dt

选C,数学书里貌似有.

函数没有返回值,函数的形式参数部分也不对,应该是fun（inta,intb）的形式
