Binary Number to Decimal using functions


Write a C++ Program to Convert Binary Number to Decimal using functions. Here’s simple C++ Program to Convert Binary Number to Decimal 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 Binary Number to Decimal using functions which is successfully compiled and run on Windows System to produce desired output as shown below :


SOURCE CODE : :


/*  C++ Program to Convert Binary Number to Decimal using functions  */

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

int convertBinaryToDecimal(long long);

int main()
{
    long long n;

    cout << "\nEnter any binary number :: ";
    cin >> n;

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

int convertBinaryToDecimal(long long n)
{
    int decimalNumber = 0, i = 0, remainder;
    while (n!=0)
    {
        remainder = n%10;
        n /= 10;
        decimalNumber += remainder*pow(2,i);
        ++i;
    }
    return decimalNumber;
}

OUTPUT : :


/*  C++ Program to Convert Binary Number to Decimal using functions  */

Enter any binary number :: 111111

 [ 111111 ] in binary = [ 63 ] in decimal

Process returned 0

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