Chapter 5,Problem h: Let Us C

Problem Statement:

Write a function to find the binary equivalent of a given
decimal integer and display it.

Solution:

//Ahmad Furqan

//P5.h

#include <iostream>

#include <conio.h>

using namespace std;

void num2bin(int num)

{

bool bin[25];

int i = 0;

for (i = 0; i < 25; i++)

{

bin[i] = num % 2; //divide number by 2 successively and save remainders

if (num < 2)

break;

num /= 2;

}

for (i; i >= 0; i--)

{

cout << bin[i];  //show remainders in reverse order

}

}

void main(void)

{

int num;

cout << "Enter a number: ";

cin >> num;

cout << "The binary equivalent of this number is: ";

num2bin(num);

_getch();

}
