Data Types

Type conversion

Type conversion is the process of converting one predefined data type into another data type.



Explicet type conversion is also known as type casting.

Ex
int a;
double b=2.55;
a=b; //implicit type conversion.
cout << a << endl; // this will print 2
a = int (b); //explicit type conversion
cout << a << endl; // this will print 2

Implicit Type Conversion

Type Casting(Explicit)

In c++ explicit type conversion is called type casting.
Syntax
type-name(expression) //c++ notation Ex
Average = sum/(float)i; //c notation
Average = cum/float(i); // c++ notation
