Detailed Description

Function to convert decimal number to binary representation.

Function Documentation

main()

int main

(

void

)

           {
    int number;
    std::cout << "Enter a number:";
    std::cin >> number;
 
    method1(number);
    method2(number);
 
    return 0;
}

method1()

void method1

(

int

number

)

This method converts the bit representation and stores it as a decimal number.

                         {
    int remainder, binary = 0, var = 1;
 
    do {
        remainder = number % 2;
        number = number / 2;
        binary = binary + (remainder * var);
        var = var * 10;
    } while (number > 0);
    std::cout << "Method 1 : " << binary << std::endl;
}

Here is the call graph for this function:

method2()

void method2

(

int

number

)

This method stores each bit value from LSB to MSB and then prints them back from MSB to LSB

                         {
    int num_bits = 0;
    char bit_string[50];
 
    do {
        bool bit = number & 0x01;  // get last bit
        if (bit)
            bit_string[num_bits++] = '1';
        else
            bit_string[num_bits++] = '0';
        number >>= 1;  // right shift bit 1 bit
    } while (number > 0);
 
    std::cout << "Method 2 : ";
    while (num_bits >= 0)
        std::cout << bit_string[num_bits--];  // print from MSB to LSB
    std::cout << std::endl;
}
