here is my code : #include #include #include using namespace std; int main() { float a= 3.0, b= 5.0, c = 7.1, d=8.3, e=2.2, f=3.2 , g= 6.1, product ; int h=5 ; cout << " " << setprecision(2) << a << endl; cout << "*" << setprecision(2) << b << endl; cout << "----------" << endl; product = a*b ; cout << product << endl; system ("pause") ; }
