Real number operation

Write a simple program , User input 2 Real data is stored in variables , And output their product and quotient （ Regardless of the divisor 0 The situation of ）

for example

Input ：3.1        4.2

Output ：3.100000*4.200000=13.020000

            3.100000/4.200000=0.738095

int main( )
{
     double a,b;
     scanf("%lf",&a);
     scanf("%lf",&b);
     printf("%0.6lf*%0.6f=%0.6lf\n",a,b,a*b) ;
     printf("%0.6lf/%0.6f=%0.6lf",a,b,a/b) ;
     return 0;
