编写程序求一元二次方程的根,考虑不同的根情况

请参考

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

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

对于形如a*x^2+b*x+c=0的方程可以使用下面的程序求根x=roots([abc])例如4*x^2-5*x+1=0x=roots([4-51])x=1.00000.2500祝你学习愉快!再问：是

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

a=-10;b=10;n=0;whileb-a>epst=(a+b)/2;n=n+1;if4*t^2+3*t-6==0break;elseif(4*a^2+3*a-6)*(4*t^2+3*t-6)>0

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

#include#include

#include#includevoidb1(){floatl,s,k;inta,b,c,h;printf("\n");printf("\n");printf("输入a,b,c的值\n");print
