We are given an integer number let’s say, num and the task is to firstly calculate the binary digit of a number and calculate the total digits of a number.

**Input** − int number = 50

**Output** − Count of total bits in a number are − 6

**Explanation** − Binary representation of a number 50 is 110010 and if we calculate it in 8-digit number then two 0’s will be appended in the beginning. So, the total bits in a number are 6.

**Input** − int number = 10

**Output** − Count of total bits in a number are − 6

**Explanation** − Binary representation of a number 10 is 00001010 and if we calculate it in 8-digit number then four 0’s will be appended in the beginning. So, the total bits in a number are 4.

Input the number in a variable of integer type

Declare a variable count to store the total count of bits of type unsigned int

Start loop FOR from i to 1<<7 and i > 0 and i to i / 2

Inside the loop, check num & 1 == TRUE then print 1 else print 0

Start loop while to calculate the total count of bits till number isn’t 0

Inside the loop, increment the value of count by 1 and set number >>=1

Print the count

#include using namespace std; //Count total bits in a number unsigned int bits(unsigned int number){ unsigned int count = 0; unsigned i; //display the total 8-bit number cout<<"8-bit digits of "<<number<<" is: "; for (i = 1 << 7; i > 0; i = i / 2){ (number & i)? cout<<"1": cout<<"0"; } //calculate the total bits in a number while (number){ count++; number >>= 1; } cout<<"\nCount of total bits in a number are: "<<count; } int main(){ int number = 50; bits(number); return 0; }

If we run the above code it will generate the following output −

8-bit digits of 50 is: 00110010 Count of total bits in a number are: 6
