Data abstraction refers to, providing only essential
features by hiding its background details.
example:
class result
{
int marks;
float percentage;
char name[20];
void input();
void output();
}

main()
{
bank b1;
b1.input();
b1.output();
}

in the above example, b1 is an object calling input and
output member functions, but that code is invisible to the
object b1.
