Int / Integer Data Type

How is "int" datatype used in C++?.


The "int" data type is used to represent integers. The signed range of the "int" datatype is between -2147483648 to 2147483647 and the unsigned range is between 0 to 4294967295.

Example :

#include <iostream.h>
void main()
unsigned int n = 0;
cout << "Signed integer value is:"<< n << '\n';
cout << "Bytes used by int is:" << sizeof(n);


Signed integer value is:0
Bytes used by int is:4

In the above example the "0" is also an unsigned integer value, the bytes occpied by the "int" datatype is "4".
