Easy c program (Binary -> decimal digits)

[joker_927]

I have failed to find anything on the internet that helps me with this very uninteresting program that I am trying to write for a much bigger overall program.

All I'm trying to do is take 1 unsigned 8-bit binary value (so far I have just used the char data type to store it) and I need to either:

split that binary number into its 3 respectful decimal digits (still in binary form for each digit)

OR

split it into its three decimal digits and have it be in BCD form.

Anyone know of an equation to do this or have or can make a simple c program that does it?

Thanks for any help

This homework?

//returns unsigned int value of binary string myString
//returns -1 on error
int binCharToInt(char* myString)
{
    int length = strlen(myString);
    int myInt = 0;

    for(int iterator = 0; iterator < length; iterator++)
    {
        myInt *= 2;

        //if 0 do nothing
        //if 1 add one to your int
        //if anything else, return 0
        if(myString[iterator] == '1')
            myInt++;
        else if(myString[iterator] != '0')
            return -1;
    }
    return myInt;
}

//returns first 3 least significant numbers in the int
//index 0 -> least significant figure
int[] split(int myInt)
{
    int[3] myIntArray;
    myIntArray[0] = myInt % 10;
    myIntArray[1] = (myInt / 10) % 10;
    myIntArray[2] = (myInt / 100) % 10;

    return myIntArray;
}

haven't compiled, tested, or run the code but if i'm thinking clearly (and right now i'm BAKING at work so i might not be thinking too clearly) that should do something along the lines of what you're looking for.
