3. Will the following lines of code in (a) and (b) print the same thing? Explain
why or why not.
(a) cout << 5 << ‘\n’;
(b) cout << “5” << ‘\n’;

4. Will the following lines of code print the same thing? Explain why or why not.
(a) cout << y<< ‘\n’;
(b) cout << “y” << ‘\n’;

Data types
C++ programming language supports various types of data. Each data type defines
its memory size, and improves the running speed of the program. C++ programming
language provides different types of data based on numeric values, Boolean values,
and characters under a specific range of values. C++ programming language is
based on three categories of data types as shown in Figure 4.23. These are built-in
or primary data types, user-defined data types, and derived data types.

Built-in or primary data types
Built-in or primary data types are pre-defined data types that can be applied directly
without creating them. Built-in data types include Integer, Character, Float, and
Bool.

(a) Integer data types
Integer data types involve whole number. Integer data types include, signed integer,
unsigned integer¸ short integer, unsigned short integer, and long integer. Table 4.3
shows the classification of integer data types with their storage size and range.
