c语言计算一元二次方程的根

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(

#include"stdio.h"#include"math.h"/*求一元二次方程ax*x+bx+c=0的解*/main(){floata,b,c,x1,x2,d;printf("请输入a：");s

//只一处有错,还有一个注意输入格式.#include#includeintmain(){doublep,q,x1,x2,disc,a,b,c;scanf("%lf,%lf,%lf",&a,&b,&c

intmain()printf("请输入a,b,c");{scanf("%d%d%d",a,b,c);intx1,x2;inty=sqrt(b*b-4*a*c);if(y>0){x1=(-b+y)/2

#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

(1)当b²-4ac

x1=(-b+Math.sqrt(Math.pow(b,2)-4*a*c))/(2*a);

double改做float再问：yiyuanercifangcheng.cpp(25):warningC4244:'=':conversionfrom'int'to'float',possiblelo

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#includeintmain(){doublea,b,c,disc,p,q,x1,x2;scanf("%lf%lf%lf",&a,&b,&c);disc=b*b-4*a*c;if(a

#include <stdio.h>#include <math.h>void main(){float a,b,c,x1,x2,di

#include//elseif(disc>0){x1=(-b+sqrt(disc))/(2*a);x2=(-b-sqrt(disc))/(2*a);printf("hasdistinctrealro

您好!很高兴为您解答.如果刨除输入格式的问题,输入的那一行“scanf("%1f,%1f,%1f",&a,&b,&c);”应该改为“scanf("

/*结束程序请按“Ctrl+z”*/#include#includeintmain(){floata,b,c;doubled,x1,x2;printf("Enterthecoefficient

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;#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=(

double类型的不能直接用==0来判断,用fabs(a)

给个算法的框架,你可以自己细化.#include"math.h"floata,b,c,delta;scanf("%f,%f,%f",&a,&b,&c);delta=b*b-4*a*c;if(delta

#include"stdio.h"#include"math.h"#include"windows.h"voidmain(){floata,b,c;printf("----计算一元二次方程ax^2+b
