Examples of data types in c++ Programming
All Contributions
C++ bool :
The bool data type has one of two possible values: true or false.
Booleans are used in conditional statements and loops (which we will learn in later chapters).
For example :
bool cond = false;C++ wchar_t :
Wide character wchar_t is similar to the char data type, except its size is 2 bytes instead of 1.
It is used to represent characters that require more memory to represent them than a single char.
For example :
wchar_t test = L'ם' // storing Hebrew character;
C++ char:
Keyword char is used for characters.
Its size is 1 byte.
Characters in C++ are enclosed inside single quotes ' '.
For example:
char test = 'h';C++ float and double:
float and double are used to store floating-point numbers (decimals and exponentials).
The size of float is 4 bytes and the size of double is 8 bytes. Hence, double has two times the precision of float
For example:
float area = 64.74;
double volume = 134.64534;As mentioned above, these two data types are also used for exponentials. For example :
double distance = 45E12 // 45E12 is equal to 45*10^12total contributions (6)
C++ void :
The void keyword indicates an absence of data. It means "nothing" or "no value".
We will use void when we learn about functions and pointers.
