Solution Review: Convert Decimal Number to Binary

Explore how to convert decimal numbers to binary by applying loops in C++. Learn the step-by-step method of dividing the number by 2 and collecting remainders to form the binary equivalent. This lesson helps you understand iterative logic and multiplication factors to build the binary result effectively.

We'll cover the following...

Solution #

C++
#include <iostream>
using namespace std;
int main() {
  // Initialize variables
  int decimal = 10, binary = 0;
  int remainder, product = 1;
  // Prints value of decimal
  cout << "Decimal Number = " << decimal << endl;
  // while block
  /*Checks if the value of `decimal` is not equal to `0`. 
  If yes, then execute line No. 17 to 21.
  If no, then execute line No. 23.
  */
  while (decimal != 0) {
    remainder = decimal % 2;
    binary = binary + (remainder * product);
    decimal = decimal / 2;
    product *= 10;
  }
  // while exit
  cout << "Binary Number = " << binary;
  return 0;
}
