C++ CHAR_BIT macro constant

CHAR_BIT constant is a macro constant which is defied in climits header, it is used to get the total number of bits of a char object, it returns the number of bits in a char object, which is 8 bits.

Note:

• The actual value depends on the compiler architecture or library implementation.
• We can also use <limits.h> header file instead of <climits> header as CHAR_BIT constant is defined in both of the libraries.

Syntax of CHAR_BIT constant:

    CHAR_BIT

Example:

    Constant call:
    cout << CHAR_BIT;

    Output:
    8

C++ code to demonstrate example of CHAR_BIT constant with climits header

// C++ code to demonstrate example of 
// CHAR_BIT constant with climits header
#include<iostream>
#include<climits>
using namespace std;

int main()
{
   //prinitng the value of CHAR_BIT
    cout<<"CHAR_BIT: "<<CHAR_BIT<<endl;
    return 0;
}

Output

CHAR_BIT: 8

C++ code to demonstrate example of CHAR_BIT constant with limits.h header file

// C++ code to demonstrate example of 
// CHAR_BIT constant with <limits.h> header file
#include<iostream>
#include<limits.h>
using namespace std;

int main()
{
   //prinitng the value of CHAR_BIT
    cout<<"CHAR_BIT: "<<CHAR_BIT<<endl;
    return 0;
}

Output

CHAR_BIT: 8
