自学c语言到顺序程序设计，这两个程序总是乱码，找不到错误的地方，求大佬帮忙#include <stdio.h>#include <math.h> void main(){double a,b,c,disc,x1,x2,p,q;scanf("%lf,%lf,%lf",&a,&b,&c);disc=b*b-4*c*a;q=sqrt(disc)/(2*a);p=-b/(2*a);x1=q+p;x2=p-q;printf("\nx1=%5.2f\nx2=%5.2f\n",x1,x2);}#include <stdio.h>#include <math.h>void main(){ double a,b,c,s,area; scanf("%lf,%lf,%lf",&a,&b,&c); s = 1.0/2*(a+b+c); area = sqrt(s*(s-a)*(s-b)*(s-c)); printf("a=%7.2g,b=%7.2g,c=%7.2g,s=%7.2g\n",a,b,c,s); printf("area=%7.2f\n",area);}很迷，搞了半天不知道哪里错了，求大佬指点
