[C++]Binary -> Decimal

Another program I wrote to help someone new...
It was quickly written

Code:

#include "stdafx.h"

#include <windows.h>

#include <iostream.h>



int toPower2(int value){

        int rtnvle = 1;

        if(value > 1)

    for(int i=2;i<=value;i++){

        rtnvle *= 2;

        }

        return rtnvle;

}



int main(int argc, char* argv[])

{

        char binary_value[16];

        int  decimal = 0;



    cout<<"Type in a binary value 16 max(remember binary is right to left): ";

        cin>>binary_value;

        

    for(int i=strlen(binary_value) -1;i >= 0;i--){

                if(binary_value[i] == '1'){

                        decimal += toPower2(strlen(binary_value) - i);

                } 

             else if(binary_value[i] != '0')

                         return 0;

        }



    cout<<decimal<<endl;

        return 0;

}

PS: I wanted to use pointers but that would of been to complex for the person I was teaching

Ok if you can't convert binary to decimal and binary to hex and hex to decimal you should not be permited to live =[

it isnt really for converting... its just source so people can learn some C++
