لإيجاد مساحة المثلث

#include <iostream.h> 
#include <math.h> 
main() 
{ 
float a,b,c,s,area ; 
cout << "\n Please enter A,B,andC: " ; 
cin >> a>> b>> c ; 
s = (a+b+c)/2 ; 
area =sqrt(s*(s-a)*(s-b)*(s-c)) ; 
cout << "\n Area = " << area ; 
}

factorial *= ( --dec) ; 
factorial *= ( --dec) ; 
factorial *= ( --dec) ; 
factorial *= ( --dec) ; 
factorial *= ( --dec) ; 
cout << "The factorial :\n (7)! = " << factorial ; 
return 0 ;
