C++编程：为什么老出现Cannot open include file: '': No such file or directory

Question

fatal error C1083: Cannot open include file: '': No such file or directory 执行cl.exe 时出错. # include <> # include<math.h> void main() {double a,b,c; pringtf("please enter a,b,c:"); scanf("%1f,%1f,%1f",&a,&b,&c); if (a+b>c && b+c>a && c+a>b) if(a=b=c) printf("等边三角形"); else if(a=b||a=c||b=c) if(c*c=a*a+b*b||b*b=a*a+c*c||a*a=b*b+c*c) printf("等腰直角三角形"); else printf("等腰三角形"); else if(c*c=a*a+b*b||b*b=a*a+c*c||a*a=b*b+c*c) printf("直角三角形"); else printf("普通三角形"); else printf("不能构成三角形");}哪里出错了，该怎么解决？
