Given a decimal number as input, we need to write a program to convert the given decimal number into an equivalent binary number.

Examples:

 
Input : 7
Output : 111

Input : 10
Output : 1010

Input: 33
Output: 100001

Algorithm for Converting Decimal to Binary:

• Step 1: Divide the number by 2 and store the remainder in an array (modulus operator).

• Step 2: Divide the number by 2 using the formula / (division operator)

• Step 3: Repeat step 2 until the result is greater than zero.

Program Code:

#include <iostream>
using namespace std;

void decimalToBinary(int n){
 int arr[11], i = 0, num = n;
    
    // Until the value of n becomes 0.
 while(n != 0){
  arr[i] = n % 2;
  i++;
  n = n / 2;
 }
 cout << num << " in Binary is ";

 // Printing the array in Reversed Order.
 for(i = i - 1; i >= 0;i--){
  cout << arr[i];
 }
 cout << endl;
}
int main() {
 int n = 156;
 decimalToBinary(n);

 return 0;
}

Output:

156 in Binary is 10011100
