Type Conversion and Casting

In programming, it is common to assign one type of variable to another. For example, you 

might want to assign an 

int

 value to a 

float

 variable, as shown here:

int i;

float f;

i = 10;

f = i; // assign an int to a float

When compatible types are mixed in an assignment, the value of the right side is 

automatically converted to the type of the left side. Thus, in the preceding fragment, the 

value in
