CHAR_BIT in C++

The CHAR_BIT is the number of bits in char. It is declared in “limits.h” header file in C++ language. It is of 8-bits per byte.

Here is an example of CHAR_BIT in C++ language,

Example

 Live Demo

#include <bits/stdc++.h>
using namespace std;
int main() {
   int x = 28;
   int a = CHAR_BIT*sizeof(x);
   stack<bool> s;
   cout << "The number is : " << x << endl;
   for (int i=1; i<=a; i++) {
      s.push(x%2);
      x = x/2;
   }
   cout << "The number of bits in a byte : " << CHAR_BIT << endl;
   for (int i=1; i<=a; i++) {
      cout << s.top();
      s.pop();
      if (i % CHAR_BIT == 0)
      cout << " ";
   }
   return 0;
}

Output

The number is : 28
The number of bits in a byte : 8
