A Program to Convert Decimal to Binary
In this example, we are giving a program to convert a number from decimal to binary.
Program to convert decimal to binary:
#include <iostream>#include <cmath>using namespace std;long long convert(int n);int main() {int n;cout << "Enter a decimal number: ";cin >> n;cout << n << " in decimal = " << convert(n) << " in binary " << endl;return 0;}long long convert(int n) {long long bin = 0;int rem, i = 1, step = 1;while (n != 0) {rem = n % 2;cout << "Step " << step++ << ":" << n << "/2, Remainder = " << rem << "Quotient = " << n/2 << endl;n /= 2;bin += rem * i;i *= 10;}return bin;}
Output:
Enter a decimal number: 19 Step 1: 19/2, Remainder = 1, Quotient = 9 Step 2: 9/2, Remainder = 1, Quotient = 4 Step 3: 4/2, Remainder = 0, Quotient = 2 Step 4: 2/2, Remainder = 0, Quotient = 1 Step 5: 1/2, Remainder = 1, Quotient = 0 19 in decimal = 10011 in binary
