编写程序,输入一元二次方程的三个系数,判断该方程是否有实根

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

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

希望有用,敬请采纳^_^#include#includeintmain(){voidroot2(doublea,doubleb,doubledisc);//定义方程有两个根时的函数voidroot1(

//Equation.h#ifndef_Equation_h#define_Equation_hclassEquation{private:doublea;doubleb;doublec;voidSh

对于ax^2+bx+c=0intpanduan(inta,intb,intc){intm;m=b*b-4*a*c;return(m);}voidmain(){inta,b,c,flag,x1,x2,t

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

PublicClassForm1PrivateSubButton1_Click(ByValsenderAsSystem.Object,ByValeAsSystem.EventArgs)HandlesB

以下程序在jdk5.0测试通过importjava.util.Scanner;publicclassTest{//一元二次方程式解法privatestaticXfx(inta,intb,intc)th

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

请参考

#include#includevoidmain(){floata,b,c,disc,x1,x2,realpart,imagpart;scanf("%f,%f,%f",&a,&b,&c);/*以a,b

我也刚学C,费了好几个小时,终于把这个问题搞定了!已经运行过了,结果跟谭版结果一样,敬请放心使用.#include"stdio.h"#include"math.h"voidmain(){doublea

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

自己写的代码,应该跟你们学校要求的差不多：（VB）首先搞三个text框,分别输入系数a,b,c；再一个command按钮PrivateSubCommand1_Click()a=Val(Text1.Te

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

publicstaticmain(String[]arg0){if(arg0==null||arg0.length==0){\x09System.out.println("请输入参数：a,b,c");
