What are Basic datatypes in C++? code example

Example 1: All data types in C++

Data Type 										Size
int (Integer) = 5, 6, 7							2
float (Floating Value) = -3.67, 2.67			4
double (Double of float) = -7.8746				8
char (Character) = 	'a', 'b', 'A'				1
string (Multiple chars) = "Hello World" 		No of Chars
bool (Boolean) = true, false					true = 1, false = 0

Example 2: data types in c++

int myNum = 5;               // Integer (whole number)
float myFloatNum = 5.99;     // Floating point number
double myDoubleNum = 9.98;   // Floating point number
char myLetter = 'D';         // Character
bool myBoolean = true;       // Boolean
string myText = "Hello";     // String
