Decimal Number to Binary using functions

Write a C++ Program to convert Decimal Number to Binary using functions. Here’s simple C++ Program to convert Decimal Number to Binary using functions in C++ Programming Language.

What are Functions ?

Function is a block of statements that performs some operations. All C++ programs have at least one function – function called “main()”. This function is entry-point of your program.

A function declaration tells the compiler about a function’s name, return type, and parameters. A function definition provides the actual body of the function.

Defining a Function : :

The general form of a C++ function definition is as follows:

return_type Function_Name( list of parameters )
{
//function’s body
}

• return_type : suggests what the function will return. It can be void, int, char, some pointer or even a class object.
• Function_Name : is the name of the function, using the function name it is called.
• Parameters : are variables to hold values of arguments passed while function is called. A function may or may not contain parameter list.
• Function body : is he part where the code statements are written.

Below is the source code for C++ Program to convert Decimal Number to Binary using functions which is successfully compiled and run on Windows System to produce desired output as shown below :

SOURCE CODE : :

```/*  C++ Program to convert Decimal Number to Binary using functions */

#include <iostream>
#include <cmath>
using namespace std;

long long convertDecimalToBinary(int);

int main()
{
int n, binaryNumber;

cout << "\nEnter any decimal number :: ";
cin >> n;
binaryNumber = convertDecimalToBinary(n);

cout <<"\n [ " << n << " ] in decimal = [ " << binaryNumber << " ] in binary" << endl ;
return 0;
}

long long convertDecimalToBinary(int n)
{
long long binaryNumber = 0;
int remainder, i = 1, step = 1;

while (n!=0)
{
remainder = n%2;
n /= 2;
binaryNumber += remainder*i;
i *= 10;
}
return binaryNumber;
}```

OUTPUT : :

```/*  C++ Program to convert Decimal Number to Binary using functions */

Enter any decimal number :: 30

[ 30 ] in decimal = [ 11110 ] in binary

Process returned 0```

Above is the source code for C++ Program to convert Decimal Number to Binary using functions which is successfully compiled and run on Windows System.The Output of the program is shown above .
