Type Conversion and Expressions
Type conversion changes a value from one data type to another.
Implicit Conversion
The compiler automatically converts one type into another when required.
int a = 10;
float b = a;Explicit Conversion
The programmer can explicitly convert a value using a cast.
float result = (float)10 / 3;Expressions
An expression combines variables, constants and operators to produce a value.
int result = (10 + 5) * 2;Understanding expressions and type conversion is important for writing correct calculations.
