4.6 Modification of expression type during assignment

------------------------------------------------------

If a type different from the type of variable to be calculated is

written after the equal sign, all variables involved in the calculation

will be converted to this new type, and only the final result will be

converted to the type of the variable being calculated. For example:

int i, a;

int i, a;

char c;

i = a * b + c ;

The variables a, b, and c in this example will be converted before

calculation to type 'int' (variable type 'i'). But if the expression is

instead written as:

i = long a * b + c ;

then a, b, and c in this example will be converted before calculation

to type 'long', and the final result will be converted to type 'i'

(integer).
