Convert Binary Number to Octal and vice-versa, Convert Octal Number to Decimal and vice-versa, Subtract Complex Number Using Operator Overloading. It is also called bit-level programming, and it is mainly used in numerical computations for a faster calculation because it consists of two digits - 1 or 0. Suppose n = 1101. Logic to convert decimal to binary number: 1. At each iteration, a while loop checks the binary number condition and validates the given number should not be less than 0; otherwise, it exits from the loop. Step 2: Divide the number by 2 using the "/ " (division operator) Step 3: Keep repeating steps 1 and 2 until the total is larger than zero. It is also known as the base 2 numeral system because it has two bits, 0s, and 1s. Similarly, In each iteration we are shifting mask variable by 1 to right and ANDing the mask with number. Above program is just to know the size of integer variable in C Programming (Borland C/C++ Compiler.) Same, if true for: b = a >> 10000000000 Here, you're doing the right shift by 10000000000 the value of b is still 0b00. Create a loop that runs until the binary number is 0.
