有没有懂哥能看出来哪里不符合题意吗？还有地方没考虑到！#include <iostream>#include <cstdio>#include <math.h> using namespace std;int main(){double a,b,c,x1,x2,k;scanf("%lf %lf %lf",&a,&b,&c);x1 = (-b+sqrt(b*b-4.0*a*c))/(2.0*a);x2 = (-b-sqrt(b*b-4.0*a*c))/(2.0*a);if(a!=0){if(b*b==4.0*a*c){printf("x1=x2=%.5lf",x1);}else if(b*b>4.0*a*c){printf("x1=%.5lf;x2=%.5lf",x1,x2);}else if(b*b<4.0*a*c){x1= -b/(2.0*a),k=sqrt(4.0*a*c-b*b)/(2.0*a);x2= -b/(2.0*a);printf("x1=%.5lf+%.5lfi;x2=%.5lf-%.5lfi",x1,k,x2,k);}}else{ printf("不成立"); }return 0;}
