Types can be converted to other types. For example, built-in types can be converted to other built-in types. Here we will discuss the implicit and explicit conversions.

33.1 Implicit Conversions

Some values can be implicitly converted into each other. This is true for all the built-in types. We can convert char to int, int to double, etc. Example:

int main()

{

    char mychar = 64;

    int myint = 123;

    double mydouble = 456.789;

    bool myboolean = true;

    myint = mychar;

    mydouble = myint;

    mychar = myboolean;

}

We can also implicitly convert double to int. However, some information ...
