Avoid losing number after decimal point in C++

In C++, the result of division of two integral values is an integral value although the variable used to store the result is of float or double type. This will result in losing digits after decimal point.
To avoid the loss of the digits, you need to explicitly convert the nominator or denominator to float or double.
e.g.
int b=10;
int a=3;
float r=(float)b/a; //convert b to float type to avoid losing digits after decimal point
cout<<r<<endl;
