Here are some logical and interesting facts about data-types and the modifiers associated with data-types:-
1. If no data type is given to a variable, then the compiler automatically converted it to int data type.
The size of a is 4 The size of b is 4
2. Signed is the default modifier for char and int data types.
x is -1 and y is -2.
3. We can’t use any modifiers in float data type. If programmer try to use it then compiler automatically give compile time error.
[Error] both 'signed' and 'float' in declaration specifiers [Error] both 'short' and 'float' in declaration specifiers
4. Only the long modifier is allowed in double data types. we cant use any other specifier with double data type. If we try any other specifier then compiler will give compile time error.
[Error] both 'short' and 'double' in declaration specifiers [Error] both 'signed' and 'double' in declaration specifiers
